Study Notes

Plato's Theory of Knowledge

Plato explored knowledge as justified true belief, arguing that a belief must be true and justified to constitute knowledge.
He outlined different interpretations of justification, finding that simply asserting a belief's truth wasn't sufficient.
Plato investigated how knowledge distinguishes itself from true belief, finding that justification is an essential component.

Gettier's Problem

Gettier challenged the classical definition of knowledge (justified true belief).
He presented counterexamples where a belief is justified and true but not genuinely known due to luck or accident.
Gettier's work highlighted that justification alone isn't sufficient for knowledge, necessitating a deeper connection between belief, truth, and justification.

Descartes' Methodological Doubt

Descartes aimed to establish certain knowledge by systematically doubting everything he thought he knew.
Key themes included doubting sensory perceptions, the possibility of dreams, and the existence of a deceiving God.
He concluded that his own existence was the foundational truth, stated as "I think, therefore I am" ("Cogito, ergo sum").
Descartes introduced the idea of the mind (res cogitans) as distinct from the body (res extensa).

Locke's Theory of Knowledge

Locke argued against innate ideas, claiming that all knowledge comes from experience.
He proposed that the mind is a "blank slate" (tabula rasa) at birth.
Locke distinguished between primary qualities, which exist independently of perception, and secondary qualities, which do not exist apart from a perceiver.
He stressed the importance of experience in shaping our ideas and knowledge.

Hume's Theory of Causation

Hume argued that the concept of causation is based solely on habit and experience, not inherent, necessary connections.
He emphasized that we only observe sequences of events and develop causal assumptions based on repetition, not direct observation of causation.
Hume's skepticism questioned the legitimacy of reasoning from experience to make universal pronouncements (e.g., induction).

Berkeley's Idealism

Berkeley argued that only minds and ideas exist; material objects only exist when perceived or conceived.
Key concepts include "to be is to be perceived" and the idea that qualities exist in the mind.
Berkeley challenged the traditional conceptions of objects existing independently of conscious awareness.

Putnam's Brain in a Vat Argument

Putnam explored skeptical scenarios where we might be brains in a vat, experiencing simulated reality.
His arguments questioned whether we can be certain about the nature of external reality or our sensory experiences.
Putnam's argument highlighted that such a scenario is self-refuting, as the very statement implies a connection to a possible outside world.

Whewell's View of Science

Whewell argued against a purely empirical approach to science.
He emphasized the importance of using causal principles and theoretical reasoning, and not just observation, to advance scientific understanding.
He highlighted that causes are not merely observed regularities or patterns, but rather active principles or forces guiding phenomena.

Popper's Falsifiability

Popper emphasized falsifiability as a criterion for distinguishing scientific theories from non-scientific ones.
He argued that scientific theories should be testable and potentially falsifiable through evidence, and not verifiable.
Popper stressed that scientific knowledge is continually revised and refined as our understanding develops and new ideas emerge.

Turing's Imitation Game

Turing's imitation game focused on whether machines could exhibit intelligent behavior indistinguishable from humans.
The test involved natural language communication between humans and machines.
Turing's work prompted reflection on the nature of intelligence and the possibility of artificial consciousness.

Searle's Chinese Room Argument

Searle challenged the idea that computer programs could produce understanding or consciousness.
His Chinese Room thought experiment illustrated that manipulating symbols (syntax) without understanding (semantics) doesn't equate to genuine comprehension.
Searle emphasized that a computer, unlike a human, lacks the ability to relate symbols to the world around it, questioning whether computers are truly intelligent.
