Free Bachelor of Philosophy: Knowledge and Skepticism Questions and Answers — Questions and Answers
Question 1: Descartes was disappointed when he realized that many of the purported truths he had learnt in his boyhood were ______.
- false. (Correct answer)
- true.
- beyond question
- contrary to his religion
Correct answer: false.
René Descartes initiated his philosophical project by systematically doubting all his previous beliefs. He discovered that many of the 'truths' he had accepted since childhood, particularly those based on sensory experience, were unreliable and potentially false. This realization led him to seek a foundation of knowledge that was absolutely certain and indubitable.
Question 2: Descartes asserts that he might actually be _____ for all he knows.
- a god
- dreaming (Correct answer)
- perfect
- infallible
Correct answer: dreaming
In his Meditations, Descartes employs the 'dream argument' to cast doubt on sensory knowledge. He points out that there are no definitive criteria to distinguish waking experiences from dreams, meaning that for all he knows, he could be dreaming right now. This raises the possibility that all his sensory perceptions and the physical world itself might be illusory.
Question 3: Descartes asserts that a bad devil _______
- must exist if God exists
- undoubtedly exists
- could not possibly exist
- could possibly be deceiving him (Correct answer)
Correct answer: could possibly be deceiving him
Descartes introduces the 'evil demon' or 'malicious demon' hypothesis as a radical skeptical argument. He posits the possibility that an all-powerful, supremely cunning evil demon could be constantly deceiving him, making everything he perceives or believes to be true actually false. This extreme doubt aims to identify any beliefs that remain absolutely immune to deception.
Question 4: Descartes argues against believing in the senses because _____.
- sense perception is indubitable
- they never directly deceive him
- they sometimes deceive him (Correct answer)
- God allows sensory deception
Correct answer: they sometimes deceive him
Descartes' method of doubt begins by questioning the reliability of the senses. He observes that his senses have occasionally deceived him (e.g., optical illusions, distant objects appearing small). Since they have proven fallible even once, he concludes that they cannot be fully trusted as a foundation for certain knowledge, leading him to doubt all sensory information.
Question 5: Descartes affirms his identity as _____.
- a thing that cannot exist
- a thing that thinks (Correct answer)
- a body
- a dream
Correct answer: a thing that thinks
Descartes, in his *Meditations*, famously concluded "Cogito, ergo sum" (I think, therefore I am). He realized that even if everything else he perceived was an illusion or deception, the very act of doubting and thinking proved his existence as a thinking substance. Therefore, his fundamental identity was affirmed as a 'thing that thinks,' an undeniable truth amidst his radical skepticism.
Question 6: Descartes argues that _____ because he is thinking in the first place.
- he exists (Correct answer)
- he is dreaming
- he does not exist
- he is not being deceived
Correct answer: he exists
This argument is central to Descartes' philosophy, encapsulated in his phrase "Cogito, ergo sum." He reasoned that the act of thinking itself is undeniable proof of an existing subject. Even if a powerful deceiver were misleading him about everything else, the fact that he is being deceived and is thinking about it confirms his own existence as a thinking entity.
Question 7: Descartes initially assumes that everything he observes is _____.
- part of him
- undeniable
- true.
- false. (Correct answer)
Correct answer: false.
In his method of doubt, Descartes systematically questioned everything he believed to be true, including sensory experiences and even mathematical truths. He decided to treat all his observations and previous beliefs as potentially false or doubtful. This radical skepticism was a methodological tool to find an indubitable foundation for knowledge, leading him to the certainty of his own existence as a thinking being.
