## CORSO DI FILOSOFIA **Esame:** - Two modalities of exam, divided in two phases, with two registrations and two votes. - First part: Ancient and Medieval Philosophy. - Second part: Modern Philosophy. - Students can take the oral exam on the same day. - Students must choose a question or topic. **Teaching Materials:** - Uploaded cards: maps and arguments. - Notes. - History of Philosophy Manual (recommended). ### The roots of Philosophy in Greek Culture - Greek civilization had already undergone extensive cultural development when it gave rise to philosophy through myth. - Within myths, the Greeks learned and transmitted important aspects of life such as the concepts of good and evil. - The Greek word *mithos* in its pre-philosophical sense meant authentic. - The authentic announcement that guides you through life was fundamental. - At some point, people became dissatisfied with these stories and began to cultivate another form of knowledge. - This new form of knowledge aimed to disengage from myth and try to understand the world, the divine, and reality (including the cosmos) without relying on stories or religious tradition. - Philosophy was initially an attempt to create a new form of knowledge and develop a system of *episteme* (knowledge that is certain and irrefutable, based on reason and logic). ### The Development of Philosophy - There is a distinction between *episteme* and *doxa* (*doxa* is opinion or knowledge that is not certain, or knowledge that is not based on reason and logic), which is important in understanding the origins and development of philosophy. - **A *doxa* (opinion)* is a personal judgment that can be questioned or doubted. - **A *episteme* (knowledge) *is a certain, irrefutable knowledge that cannot be refuted by anyone, and questions can only be challenged with the same methods that lead to the knowledge itself. - **Socrates** did not use the terms *doxa* and *episteme*, but he made a distinction between those who are awake and those who are asleep. Those who are asleep are satisfied with what they see and live in a dream. Those who are awake seek to understand the world beyond the veil of dreams. According to Socrates, most people are asleep, and most people are not philosophers, because philosophy is for the few. ### The Philosophical Method and the Foundations of Knowledge - Philosophy uses reason and rational justifications, asserting the right to question any aspect of reality. - It rejects limitations imposed by political powers or religious doctrines. - Philosophy is critical questioning. - It is possible for everyone to reason and philosophize together. ### The importance of *philia* (passionate connection) and *sophia* (wisdom) in philosophy - The word philosophy derives from *philia* and *sophia*. - *Philia* (passionate connection) is central to the philosophy of Aristotle, who argued that without it, life is not fulfilling. - Humans must cultivate *sophia* and nurture *philia* with them. - However, *philia* alone does not constitute *sophia*. ### Truth and Revelation - For the Greeks, truth is not merely what is said, but what is revealed and manifests itself. - Truth emerges from the darkness and must be recognized by all. - The Greek word for truth, *aletheia*, is made up of A (a negative function - negation of) and *letheia* (that which is forgotten, that which is hidden). - Truth is revealed and forces us to acknowledge it because it can no longer be obscured by darkness. - Philosophy allows us to come in contact with what manifests itself out of the darkness. ### The Philosophical Question of the Human Being - Philosophy does not address immediate needs or practical urgencies. - Human beings are not just biological animals. - Philosophy recognizes the human being's surplus beyond biological life. - Philosophical questions do not have any practical use, but they are valuable for revealing the true freedom of the human being. - For the Greeks, the contemplation of truth was the ultimate expression of human freedom. - Aristotle believed that wonder is at the origin of philosophical questioning. - Human beings have always been curious about phenomena they cannot understand. - Wonder is an experience of not knowing. - Wonder is a feeling that is not under our control. ### The Importance of Wonder in Philosophy - Wonder arises from encountering something new or unexpected. - Philosophy emerges from the awareness of one's own ignorance. - There are two types of individuals: those who seek answers (philosophers) and those who are overwhelmed by their own ignorance, but do not seek answers. - This feeling of wonder was also a source of anxiety for the Greeks. - They felt anxious because everything is transient. - Philosophy was an attempt to find stability in a world of constant flux. ### Heraclitus: The Importance of Change - Heraclitus did not use the terms *doxa* and *episteme*, but he distinguished between those who are “awake” and those who are “asleep.” - Those who are asleep are content with what they see and live in a dream. - Those who are awake strive to understand the world beyond the veil of dreams. - Those who are awake are philosophers. - According to Heraclitus, most people are asleep, and philosophy is for the few. - Heraclitus is known for his famous aphorism, "Everything flows." - He believed in the constant changing of everything. - The constant movement through the universe is driven by a conflict between opposites (which he called *polemos* — war or struggle). - He viewed **“everything flows" as a continuous and endless process of becoming.** ### Parmenides of Elea: The Importance of Being - His philosophy represents a fundamental turning point in the history of philosophy. - His work is often considered the first expression of *episteme*. - Parmenides wrote a poem *On Nature* in which he was taken on a journey to a divine being who told him to remain on the path of truth. - To Parmenides, the path of truth is the path of *being*. - **The fundamental principle of Parmenides' philosophy: Being is, and cannot not be. Not Being cannot be, and cannot not be.** - The nature of *being* is not based on what is concretely real but on *being* in the abstract. - According to Parmenides, the universe is composed of *being*, and everything is a manifestation of *being*. - The Universe is not a product of change—the Universe is eternal and unchanging. ### The Parmenidean Principle and its Implications - Since there is no such thing as *not being*, it is impossible to conceive of *not being*. - Everything that is, is being. - Everything that is, is eternal, and has no origin or end, no birth, and no death. - Therefore, change and movement are mere illusions. ### Democritus: The Importance of Atoms and the Rejection of Divine Intervention - Democritus agreed with Parmenides that *not being* does not exist. - However, he disagreed with Parmenides' view of the Universe. - Democritus believed that the Universe consists of infinite atoms that constantly interact and combine in different ways. - Although there is no such thing as *not being*, there is multiplicity. - For Democritus, change, movement, and birth and death are simply expressions of the constant aggregation and disaggregation of atoms. - The movement of these atoms is eternal. - There is no purpose or end to their movement. ### The Sophistic Turn: The Importance of Human Being - In the history of philosophy, the Sophists represent a historical turning point in Greek thought. - The Sophists became increasingly influential during the period of Athenian democracy. - Their philosophy is characterized by a focus on human beings and human affairs. - This emphasis on human beings led them to shift away from the traditional concerns of cosmology and ontology, which had focused on the nature of the universe and the fundamental principles of existence. - The Sophists are also known for their emphasis on the study of: - rhetoric: the art of persuasive speaking. - politics: The art of governing. - ethics: The study of right and wrong. - They often questioned traditional conceptions of truth and justice and claimed that there is no absolute truth. - They argued that truth is relative to the individual person and their circumstances. ### The Sophistic Turn and the Rise of the Individual - During this period, the city-state of Athens became a vibrant hub of political and intellectual activity. - As Athenian democracy developed, people became increasingly interested in political and ethical questions. - The Sophists played a significant role in this developing discourse. - They used their skills in rhetoric and argumentation to influence public opinion and persuade people to their way of thinking. ### Protagoras: The Importance of Human Measure - Protagoras is famous for his statement *“Man is the measure of all things." - This statement is often interpreted in a variety of ways. - One interpretation is that for Protagoras, what is true for one person may not be true for another. - There is *no absolute truth*, but truth is relative to individual perspectives. - Another interpretation is that Protagoras believed that human beings are the ultimate arbiters of what is right and wrong. ### The Rise of Skepticism - The philosophy of skepticism emerged during this period. - Skeptics challenged the idea that humans can achieve certainty in their beliefs. - They argued that human beings are limited by their senses and perception. - Ultimately, they concluded that it is impossible to know anything for certain. ### Socrates: The Importance of Self-Knowledge - Socrates emerged as a crucial figure in the history of philosophy, deeply critical of the Sophists. - He believed in a more rigorous and searching approach to knowledge. - His philosophy emphasized the importance of self-knowledge. - Socrates thought that true wisdom lay in recognizing one’s own ignorance. - He believed that the path to self-knowledge involved engaging in open and rigorous dialogues with others. ### Socratic Method: A Dynamic Approach to Knowledge - Socrates did not write any books. - He believed that true philosophy could only be achieved through direct and open dialogue with others. - He developed a method of questioning designed to expose the limits of one's own knowledge. - Socrates famously refuted the claims of those who believed they had a great amount of knowledge by demonstrating that they were often unaware of various contradictions in their own ideas. - Through his method, Socrates aimed to help people find genuine knowledge by leading them through a process of intellectual inquiry. ### The Legacy of Socrates in the Writings of Plato - Socrates' ideas were preserved in the works of Plato and Aristotle. - Plato believed that Socrates had made a significant contribution to philosophy by emphasizing the importance of moral inquiry and virtue. - He regarded Socrates' method of questioning as a method for helping people discover true knowledge. - Despite Socrates' own emphasis on the importance of dialogue, Plato's method was to put Socrates' thoughts in a dialogical form. - Plato’s dialogues were intended to present Socrates' ideas in a dramatic and engaging way. - Through the use of dialogue, Plato was able to explore different perspectives, to reveal inconsistencies in thought, and to ultimately arrive at a deeper understanding of what it means to live a good and virtuous life. ### Plato: The Significance of Philosophy - Plato is considered one of the most important philosophers of all time. - His work was profoundly concerned with the nature of knowledge, politics, and ethics. - According to Plato, philosophy is the pursuit of truth, and this pursuit begins with an examination of the self. ### The Socratic Turn and Plato’s *Apology* and *Crito* - Socrates was ultimately condemned to death by the Athenian democracy. He was accused of corrupting the young and introducing new deities to Athens. - Socrates did not defend himself in a conventional way, but used the trial as an opportunity to further articulate his beliefs. - Plato's *Apology* is an account, written in the form of a dialogue, of Socrates' defense speech before the Athenian jury. - In the Apology, Socrates argues that his pursuit of philosophy is what enabled him to recognize the true nature of wisdom. - He claims that he is the only truly wise person, as he alone understands that he knows nothing. - The story of Socrates' trial is an example of the tension between philosophy and the political world. - It shows how those who seek truth can be persecuted by those who are in power. ### Plato’s *Crito* - Plato’s *Crito* is about Socrates' decision to remain in prison and accept execution rather than flee Athens. - It demonstrates the power of reason and the importance of laws in maintaining social order. ### The Significance of the Socratic Method and the Importance of Dialogue - Socrates never wrote anything down. - He believed that true philosophy could only be achieved through dialogue, rather than through written texts. - The dialogue process is not merely a form of communication, but a method for generating new knowledge and understanding. - It is through dialogue that we can truly understand ourselves and the world around us. - Dialogue is also the foundation of a healthy political community, as it allows for different perspectives to be shared and debated in a non-violent and peaceful manner. ### The Importance of Self-Knowledge - Socrates believed that the first step to philosophical inquiry is self-knowledge. - He famously said, "Know thyself." - This means that we should carefully examine ourselves and our beliefs. - We should never take our knowledge for granted, but constantly question and challenge ourselves. - Socrates believed that through this process of self-examination, we could develop a deeper understanding of ourselves and the world around us. ### The Socratic Method: The Art of Questioning - The Socratic Method is a critical and respectful process of guiding people through a series of questions to help them arrive at a deeper understanding of themselves and the world around them. - Socrates would begin by asking people to define a concept, such as justice or beauty. - He would then go on to ask a series of increasingly challenging questions to expose the flaws in their initial definition. - Through this process, Socrates could help people arrive at a more nuanced and sophisticated understanding of the concept. ### The Philosophical Significance of Socrates’ Irony - Socrates was famous for his use of irony, a kind of playful deception that he used to expose the limits of human knowledge. - Socrates would often pretend to be ignorant, even when he knew the answer, in order to draw others out and challenge their assumptions. - This was a key element of his method, as it allowed people to see the limits of their own knowledge and to become more open to considering alternative perspectives. - It was a technique that was intended to help people humble themselves and to recognize their limitations. > "The only true wisdom is in knowing you know nothing." — Socrates ### The Importance of Virtue - Plato believed that Socrates’ true concern was with the nature of virtue. - Socrates emphasized the importance of living virtuously and the challenges of being a virtuous individual in a world that often valued wealth, power, and social status over moral principles. ### The Role of The "Daimon" in Socrates’ Philosophy - The Daimon is a recurring character in Plato’s dialogues, but the nature of the Daimon is a matter of debate. - According to some interpreters, the Daimon may have been a personal voice of guidance from God while, according to others, the Daimon may have been simply part of Socrates’ internal consciousness or sense of morality. ### The Relationship between Knowledge and Action in Socratic Philosophy - Socrates believed that knowledge was the foundation of virtue: a key concept in Socratic philosophy. - He argued that people do wrong because *“they do not know what is right." - This is often called the "Socratic paradox." - The idea is that if people fully understood what was right, they would always choose to do what was right. ### The Limits of Knowledge in Plato's Philosophy - Socrates’ own philosophy was ultimately limited by the fact that he did not write any of his ideas down. - It is largely through Plato’s dialogues that we have come to understand Socrates’s ideas. - The nature of the relationship between Socrates’s ideas, as they appear in Plato's writings, and his own philosophy is a matter of debate. - Some scholars claim that Plato was true to Socrates, while others argue that Plato's version of Socratic philosophy was significantly different from Socrates' real philosophy. - This is a testament to the enduring influence of Socrates' ideas, but it also highlights the complexities of preserving and interpreting philosophical thought across history. ### Plato’s Emphasis on Philosophy as a Cure for the Soul - Plato believed that philosophy could act as a cure for the ‘soul’. - He saw philosophy as a way to guide people toward virtue and to help them lead a more fulfilling life. - He believed that *“the unexamined life is not worth living.”* ### The Importance of Dialogue in Plato’s Philosophy - According to Plato, true philosophy is not a solitary pursuit: The path to knowledge and truth is achieved through engaging in **dialectic**. - **Dialectic** is a process of discussion and debate, where opposing ideas are critically examined and challenged. - Plato believed that through this process, we could arrive at a greater understanding of truth. - Plato's *Republic* is a key work in his philosophy, which demonstrates the role of dialogue in the journey toward wisdom. ### The Philosophical Significance of Plato’s *Republic* - Plato’s *Republic* is an influential work in political philosophy. - It aims to describe what a just society would look like. - Plato’s *Republic* posits an ideal society that is founded on the principles of justice, reason, and morality. - He contends that this just society can be achieved through the careful selection of rulers, the establishment of appropriate laws, and the education of its citizens. ### The Similarities and Differences between Socrates and Plato - While Plato is a great admirer of Socrates, his philosophy diverges from Socrates in key ways. - Socrates focused on the importance of self-examination and living a virtuous life, while Plato was more interested in establishing a framework for a just society. - Socrates was content to engage in dialogue and to challenge others to think critically, but Plato envisioned a more systematic and organized approach to philosophy. - In essence, while Plato admires Socrates’s method, he takes those ideas and reimagines them to form his own perspective. ### Plato’s Philosophy and the Nature of the Soul - Plato’s *“Theory of Forms”* is an effort to understand the nature of reality and to distinguish between the world of appearances and the world of true reality. - He argued that the world of experience is a shadow of the true world of Forms, which are unchanging, eternal, and perfect. - Plato’s philosophy of the soul is closely tied to his theory of Forms. - He viewed the soul, which is immortal, as a fundamental component of human existence. - According to Plato, the soul is divided into three parts: * the rational part (logos or reason) * the spirited part (thumos or emotions) * the appetitive part (epithumia or desires). - The rational part is the most important part of the soul. It is responsible for making moral judgments, pursuing knowledge, and controlling the other parts of the soul. ### Plato's Theory of Forms and the Importance of Education - Plato believed that education was essential for helping people to understand the world of Forms and to achieve virtuous living. - He believed that through a process of education, people could learn to reason properly, to control their desires, and to develop a strong sense of what is right and wrong. - Plato’s *Republic* is a vision of a just society where education is central to the wellbeing and happiness of its citizens. ### The Significance of Plato's Theory of Forms for Western Philosophy - Plato’s *“Theory of Forms”* has had a significant impact on Western thought. - It has influenced theologians, artists, and philosophers for centuries. - Many philosophers have found it helpful to distinguish between the world of appearances and the world of true reality. - Even those who disagree with Plato’s theory of Forms, such as Aristotle, believe that Plato’s distinction between the real and the apparent is important for understanding the human condition. ### Aristotle: A New Direction in Philosophy - Aristotle was a student of Plato, but his philosophy diverged from Plato’s in key ways. - While Plato believed in the existence of a world of Forms that lay beyond the real, Aristotle rejected this view. - He argued that the Forms do not exist in a separate realm but are immanent, or inherent, in the things that we experience. - Aristotle’s philosophy is also more grounded in experience and the natural world—philosophy is about understanding how things work. ### The Key Concepts of Aristotle’s Philosophy - Aristotle made significant contributions to many areas of philosophy, including logic, physics, biology, ethics, politics, and metaphysics. - His approach to philosophy was more systematic and empirical than Plato's. - He believed that philosophy should start with careful observation and then proceed to develop general principles through logical analysis. ### The Importance of "Substance" in Aristotle’s Philosophy - For Aristotle, *substance* is the most fundamental concept in metaphysics, or the study of being. - He defined *substance* as the kind of thing that exists independently, or that is not dependent on something else for its existence. - Aristotle identified several kinds of substances, including: * *individual* substance * *natural* substance * *artificial* substance. ### Aristotle’s Explanation of "Change" and the Relationship between "Form" and "Matter" - Aristotle believed that all change is a process of *becoming*. - He argued that change involves a transformation of something *potential* into something *actual*. - Change is possible because all things are composed of both *form* and *matter*. - *Form* is the essence, or defining characteristic, of something. - *Matter* is the raw material out of which things are made. - Change involves a change in the form of matter. - Aristotle's theory is widely known as the *“hÿlemorphic theory ”* (hyle = matter). ### Aristotle’s Concept of "Cause" - Aristotle believed that in order to understand the world, it was necessary to understand the causes of things. - He identified four different types of causes: * *material* cause * *formal* cause * *efficient* cause * *final* cause - The **material cause** is what something is made of. - The **formal cause** is the shape or essence of something. - The **efficient cause** is whatever brought the thing into existence. - The **final cause** is the purpose or end of a thing. - Aristotle believed that to understand a thing, we must understand not only what it is made of or what it is like, but why it exists and what its ultimate purpose is. ### The Importance of "First Philosophy" for Aristotle - Aristotle called his own metaphysics *“First Philosophy”* because he believed it was the most fundamental philosophical discipline. - Metaphysics is the study of being, and to Aristotle, it was essential for understanding the nature of the world, including the human condition, right and wrong, and the nature of God. ### The Relationship Between Aristotle’s Metaphysics and Theology - Aristotle's understanding of the *unmoved mover* is often interpreted as a reference to God. - Although Aristotle’s ideas had a significant influence on Christian theology, he was not a Christian. - His works were studied and debated throughout the Middle Ages, and many Christian thinkers sought to integrate Aristotle’s ideas with their own beliefs. ### The Influence of Aristotle’s Philosophy on Medieval Philosophy - Augustine, a key figure in early medieval philosophy, was influenced by Plato. - Thomas Aquinas, an important figure in later medieval philosophy, was influenced by Aristotle. - Aristotle’s philosophy had a significant impact on medieval philosophical thought. - It provided a framework for understanding the world and for thinking about the nature of God. ### Anselm of Canterbury: A New Approach to Theology - Anselm was an influential medieval theologian. - He played a significant role in the development of Christian theology. - He is famous for his *ontological argument* for the existence of God: a proof that attempts to demonstrate God’s existence based on the concept of God rather than through observation or experience. - Anselm argued that God is *“that than which nothing greater can be conceived.”* - Since it is impossible to imagine an all-perfect being that does not exist, it follows that an all-perfect being *must* exist. ### The Philosophical Significance of Anselm’s Argument - Anselm’s ontological argument has been a source of debate and controversy among philosophers for centuries. - Some critics argue that the argument is invalid because it relies on the assumption that just because we can conceive of something, it must logically exist. - Others defend the argument, claiming that it is a legitimate proof of God’s existence because it relies on the concept of God as a being that has all perfections. - Regardless of whether one accepts Anselm’s argument, it has influenced many philosophers and theologians who have sought to understand the relationship between faith and reason. ### Thomas Aquinas: The Importance of “Faith and Reason” - Thomas Aquinas is a key figure in the development of Medieval Theology. - He sought to systematize the philosophy of Aristotle, and to integrate it with Christian theology. - He is famous for his *“Five Ways”* (also called "The Five Proofs") to demonstrate the existence of God. ### Aquinas’ Five Ways The Five Proofs are based on empirical observations of the natural world. They are: 1. **The Argument from Motion:** The existence of motion in the world implies the existence of a *first mover*, which is unmoved itself. 2. **The Argument from Efficient Causes:** The existence of a series of efficient causes requires that every cause is caused by something else. This implies the existence of a *first cause*, which is uncaused itself. 3. **The Argument from Contingency:** The existence of contingent beings (those that are not necessary and could not have existed) implies the existence of a *necessary being*, upon which contingent beings depend for their existence. 4. **The Argument from Degrees of Perfection:** The existence of various degrees of perfection in things suggests the existence of a *perfect being*, which is the source of all perfection. 5. **The Argument from the Teleological Order of the Cosmos:** The natural world exhibits order and purpose. This implies the existence of an intelligent designer, which is the *first cause*. Aquinas argues that these Five Ways, combined with reason, demonstrate the existence of God. ### Aquinas and the Relationship Between “Faith and Reason” - According to Aquinas, faith and reason are complementary. - He argued that even though faith is a gift from God, reason can help us to understand the truth of faith. - Aquinas believed that faith and reason are essential to true knowledge and are not in conflict with each other. ### The Key Ideas of Aquinas’ Philosophy - Aquinas’s philosophy had a profound impact on the development of Western thought, and his ideas continue to be discussed and debated today. - Here are some of his key ideas: * **The existence of God:** Aquinas argued that God’s existence can be proven through reason. * **The nature of knowledge:** Aquinas believed that knowledge is obtained through both faith and reason. * **The nature of the soul:** Aquinas believed that the soul is immortal and that it survives bodily death. * **The nature of morality:** Aquinas believed that moral principles are based on natural law and the will of God. ### The Influence of Aquinas’ Philosophy - Aquinas’s philosophy has been influential in a wide range of areas, including: * philosophy * theology * ethics * political thought. - His work is still widely studied and debated today. ### The Development of Scholastic Philosophy - The emergence of universities in the 12th century marks a significant shift in the history of philosophy. - Prior to this period, philosophical inquiry was largely confined to monasteries. - Universities, with their focus on systematic learning, provided a new venue for the pursuit of knowledge. - They created a new form of education, known as scholasticism. - The Scholastic method was characterized by its emphasis on logic, argumentation, and the systematic analysis of texts, especially the writings of Aristotle. - Scholastic philosophers sought to reconcile the teachings of the Church with the findings of reason. - Their goal was to harmonize faith and reason. ### The Rise of “Ockham’s Razor” - William of Ockham was an influential philosopher of the 14th century. - He is famous for his *“Ockham’s Razor,”* which states *“Entities should not be multiplied beyond necessity”*. - This principle means to favor explanations that use the fewest assumptions and simplest explanations. - Ockham's Razor was an influential principle in the history of science as well as philosophy. - Ockham’s philosophy stressed the importance of empirical evidence and the limits of human reason. - He argued that it is impossible to prove the existence of God through reason. - Ockham believed that faith was a matter of revelation, not of reason or logic. ### The Move Away from Scholasticism - Ockham's philosophy played an important role in the decline of Scholasticism. - His skepticism about the limits of reason and the importance of empirical observation helped to pave the way for the development of modern philosophy. ## A Brief Conclusion - The Middle Ages were a time of intellectual ferment in Europe. - Philosophers of this period were concerned with reconciling faith and reason and understanding the nature of God, the human condition, and the world. - The contributions of philosophers such as Anselm, Aquinas, and Ockham continue to be relevant and debated today. Their work provides us with a rich tradition of philosophical thought that continues to inform and shape our understanding of the world.
