PHILOSOPHY – LESSON 2 KNOWING THE TRUTH 3. Contingent Truth sometimes expressed by saying that a contingent proposition NATURE OF TRUTH is one that is true in some possible worlds and not in others "It is raining outside right now" is contingent because it is There are two conflicting philosophical views about this true at this moment but not necessarily true at all times. question: those who affirm that truth indeed has a specific "The Eiffel Tower is in Paris" is contingent because it could nature and those who deny it. have been built elsewhere in a different world. o Those who affirm that truth has a specific nature see truth "The car is blue" is contingent since the car could have been as a substantial property. The motivating idea behind this is painted a different color in another circumstance. that by ascribing “is true,” “it’s true,” or any of its cognates 4. Necessary Truth to a given truth-bearer something theoretically significant is a true statement whose negation must imply a contradiction being added to it. in reality, such that the negation would be impossible o Those who deny this claim that when we say that a given "A triangle has three sides" is a necessary truth because truth-bearer is true, the predicate “is true” does not add denying it would lead to a contradiction. anything significant to it at all. "All humans are mortal" is a necessary truth since being ❖ A variety of truth-bearers are considered – statements, beliefs, mortal is part of the definition of being human. claims, assumptions, hypotheses, propositions, sentences, and "The sum of the angles in a triangle is 180 degrees" is a utterances. necessary mathematical truth that cannot be denied without ❖ Proposition refers to a linguistic expression whose function is to contradiction. advance a claim about the world. 5. PRIVATE TRUTH ❖ Propositions are distinguished as the primary bearers of truth, can only be known by the person who has the belief or make while sentences and utterances are properly characterized as the statement considered to be true. true in virtue of expressing true propositions. "I am feeling happy today" is a private truth known only to ❖ Beliefs are the mental expressions of our claims. Sometimes it is the person experiencing the emotion. said that statements are expressions of beliefs, which means "I believe in life after death" is private since only the beliefs as more basic than statements. individual can truly know their belief. "I have a headache" is private because only the person Differences of Fact and Truth experiencing it can know if it's true. FACT TRUTH 6. PUBLIC TRUTH Objective Subjective is a kind of truth known by everyone. Empirical Evidence only Based on evidence, but with "The Earth revolves around the sun" is a public truth known personal and cultural perspective and accepted by everyone. Specific Broader "Barack Obama was the 44th President of the United States" is a public truth because it is widely recognized. KINDS OF TRUTH "Water is composed of hydrogen and oxygen atoms" is a public truth known through scientific consensus. 1. Empirical Truth 7. SUBJECTIVE TRUTH described as a posteriori which means that it can only be is dependent on the attitudes, preferences or interests of a known after some relevant experience. person or a group of persons The statement "Water boils at 100°C at sea level" is true "Chocolate ice cream is the best flavor" is a subjective truth based on experimental observation. based on personal preference. "The sun rises in the east and sets in the west" is an "This movie is entertaining" is subjective, as different people empirical truth based on repeated daily experience. may have different opinions. "Ice melts at 0°C under normal atmospheric pressure" is "Running is a fun activity" is dependent on the individual's true only after the relevant experience of observing ice interest in running. melting. 8. Objective Truth 2. Rational Truth is an objective claim is a statement about a factual matter, called a priori which means that it can be known before some one that can be proved true or false. relevant experiences. "The Earth is approximately 93 million miles away from the "All bachelors are unmarried" is a rational truth because it Sun" is an objective truth that can be scientifically verified. is true by definition without requiring experience. "The Pacific Ocean is the largest ocean on Earth" is an "2 + 2 = 4" is known to be true through logic and reason, objective fact that can be measured. independent of experience. "Humans require oxygen to survive" is an objective truth "If it is raining, then there are clouds in the sky" is true that applies to all people and can be proven. based on the logical connection between rain and clouds.  PHILOSOPHY – LESSON 2 9. Universal Truth Examples: when a belief or a statement is acknowledged to be true by a) "2 + 2 = 4": This statement is true because it coheres with everyone the system of mathematics, where the rules and logic "All humans need food and water to survive" is universally consistently support this outcome. accepted as true by everyone. b) "All humans are mortal": This belief is coherent with our "Fire burns" is a universal truth acknowledged by all people understanding of biology and human existence, fitting within due to its obvious effects. the broader network of beliefs about life and death. "The Earth has gravity" is a universally recognized truth c) "Democracy is a fair form of government": This experienced by everyone on Earth. statement may be seen as true within a coherent system of 10. Relative Truth beliefs that values equality, freedom, and public when a belief is acknowledge only by some people. participation in decision-making. "In some cultures, it is customary to remove shoes before entering a home" is true for some cultures but not all. 3. Pragmatic Theory "Abortion is morally acceptable" may be true for some William James is considered the father of pragmatism. A individuals or societies but not for others. sentence is meaningful only if believing it would make a "Spicy food is enjoyable" is a relative truth, as not everyone practical difference in your life as opposed to believing some shares the same taste preferences. alternative to it. Explanation: The Pragmatic Theory, associated with William James, THEORIES OF TRUTH asserts that a belief or proposition is true if accepting it leads to practical consequences or benefits in one's life. According to this view, truth is 1. Correspondence Theory determined by the practical effects of a belief—if believing something helps proposes that a proposition is true if it corresponds to the one navigate the world effectively, then that belief is considered true. Truth facts. Often traced back to Thomas Aquinas’ version: “A is not an abstract ideal but rather a tool for achieving desired outcomes. judgment is said to be true when it conforms to the Examples: external reality” (Summa Theologiae, Q. 16). a) "Exercising regularly improves health": This belief is true Explanation: The Correspondence Theory asserts that a statement or pragmatically because acting on it leads to improved proposition is true if it accurately reflects or corresponds to reality or physical well-being, making a practical difference in life. facts. In other words, a belief or judgment is considered true if it matches b) "Wearing a seatbelt reduces the risk of injury in a car what is actually the case in the external world. This theory traces back to accident": This statement is pragmatically true because philosophers like Thomas Aquinas, who believed that truth occurs when following it leads to better safety outcomes in accidents, as thought or judgment aligns with real-world facts. verified by its practical results. Examples: c) "Studying increases your chances of passing an exam": a) "The sky is blue": This statement is true because it This belief is pragmatically true because acting on it typically corresponds to the fact that, under normal conditions, the leads to better academic performance, which makes a sky appears blue to observers. practical difference for students. b) "Water freezes at 0°C": This proposition is true because it corresponds to the physical fact that water changes state METHODS IN PHILOSOPHIZING to ice at this temperature under standard atmospheric pressure. Philosophy of Man c) "There are 50 states in the United States": This The British philosopher Karl Raymund Popper (as cited in statement is true because it corresponds to the factual Demetrio, 2001) theorized that man concurrently exists in three number of states in the U.S. distinct worlds: (1) the physical world of nature 2. Coherence Theory (2) the internal world of ideas, thoughts, and emotions Preferred by many idealists. For idealists, reality is like a (3) the social world of inter-subjectivity. collection of beliefs, which makes the coherence theory Philosophy of the Human Person can be defined as the science of particularly attractive. human beings that interprets the data of experience in the light of Explanation: The Coherence Theory of truth holds that a belief or metaphysical principles. proposition is true if it fits coherently within a larger system of beliefs or Philosophy of Man is as broad as life and as deep as human statements. Rather than depending on external facts, truth here is understanding, since it looks into the wholeness and fullness of determined by how well a proposition aligns with other accepted truths or human existence. Philosophy of Man is an inquiry into the what- beliefs. This theory is often favored by idealists who view reality as who-and-why of man. interconnected, and coherence among beliefs as essential for establishing truth.  PHILOSOPHY – LESSON 2 Approaches in Understanding Man 2. Transcendental Method 1. The descriptive (or scientific) approach asks about what is man Aspect Transcendental Method as person, as a nature, and as existing. It is merely interested in Origin Immanuel Kant describing man’s personhood, nature, and condition. It uses Focus Conditions that make experience and knowledge empirical method and explains that there is no knowable reality possible beyond what one can see, hear, measure, etc. Purpose To uncover the a priori (pre-experiential) Examples: conditions that structure experience a) "Humans have 23 pairs of chromosomes": This is a Approach Investigates the structures of consciousness factual, scientific statement about human biology, based on that allow for the possibility of experience empirical research and observation.

The normative (or prescriptive) approach asks what man as a (Epoché) conditions rather than suspending judgment person, as a nature, as existing is suppose to be.

Explanation: The phenomenological method, developed by Edmund Husserl, Examples: focuses on the study of human experiences as they are perceived by 1.

Methodology Descriptive: Focuses on describing the lived 2. Exploring the nature of causality: Instead of just observing experience cause-and-effect relationships, a transcendental philosopher would Use of Bracketing Central: Bracketing is used to set aside biases ask what conditions must exist in the mind for us to understand (Epoché) and focus purely on the experience events in terms of causality, focusing on the underlying cognitive frameworks that shape this understanding.  PHILOSOPHY – LESSON 2 Critical Thinking as Method that Leads to Wisdom and Truth Example: "I think online education is more effective than 1.
