Rationalism Flashcards
What are the three different ways for Rationalists to have A priori knowledge?
- Intuition
- Deduction
- Innatism
Define ‘intuition’
An immediate apprehension of a self-evident truth
For example, “the shortest distance between two points is a straight line” is not something we need to experience every time
Define ‘deduction’
Logically demonstrating something without reference to sense experience
e.g. Mathematics
List the premises of Descartes’ Trademark Argument
- The cause of anything must be as great as it’s affect
- My ideas must have a cause
- I am imperfect
- I have an idea of God who is perfect
Therefore, God must have caused the idea and he must exist
Outline two criticisms of Descartes
- Avalanches can be caused by small sounds, so Descartes says a cause must be as great as it’s effect is not always true
Reply
-The small sound would not be the “total and efficient cause”, as gravity and snow buildup are also a factor
Explain Leibniz’ Law of Non-Contradiction
You CAN have knowledge that you are not conscious of as most young children wouldn’t be able to explain the Law of Non-Contradiction yet would not try to both open and close a door simultaneously
Briefly explain Chomsky’s argument for Innatism
- Children are fluent in their native language by age 4 without explicit teaching
- This includes forming sentences they have never heard before
- Supported by the “Wug test”
Outline an objection of Chomsky’s Innatism
Locke:
If you were to ask a child about the rules of the grammar they were using, they probably wouldn’t be able to explain them. For Locke this doesn’t count as knowledge
Explain what is meant by ‘Plato’s Forms’
- Plato believed that our mind’s image of a triangle is an “ideal triangle” is something we grasp through ‘reason’ as we have never experienced such a triangle (This also applies to numbers)
- He named these ideal concepts as FORMS
- This helps solve the ‘problem of universals’, meaning our concepts of beauty and justice are not copies of sense impressions
- Slave Boy example
Outline a criticism of Plato’s Forms (include reply)
- Forms are metaphysical and we exist in the physical world. Plato is relying on a non-natural kind of thing to explain our knowledge, which empiricists would argue cannot be properly justified
Reply
The two distinct realms of the physical and non-physical world are connected by our rationality, much like we can use rationality to connect with non-physical mathematical truths
Define ‘conceptual scheme’
A set of concepts used to organise our experience of the world
Explain Kant’s Conceptual Schemes
- Our minds are not blank slates at birth but rather contain conceptual schemes to categorize information information
- Kant believes experience would be meaningless if it was just stored as a jumble of colours, sounds etc…
- These innate concepts include: space/time/causation
- Kant rejects Hume’s idea that all a priori knowledge is analytic, and believes there can be synthetic a priori knowledge (e.g. every event has a cause)
Outline a criticism of Kant’s Conceptual Schemes
The “sapir-whorf” argument:
- There are not universal conceptual schemes, but rather different cultures use different categories
- For example: American Hopi Indians developed their own sense of time, past and future
