Kant Groundwork, Chapter 3
The will: the ability to act according to the thought of laws.
This means that the will, for Kant, is something only rational agents have.
Autonomy vs. heteronomy
Autonomy: the wills ability to give laws to itself.
Theaetetus (up to 155e)
Early on, Socrates suggests that we should only defer to experts.
If experts are those with knowledge, then we need to know what knowledge is to know who to defer to.
First attempt at defining 'knowledge'
Theaetetus's first definit
Review: Knowledge as perception
Any instance of knowledge has the form: It seems to S that x is F.
All truths (the objects of knowledge) are of the form: x is F for S.
In other words: F is predicated of x only relative to S. It might
The challenge: defending a non-relativist view.
Knowledge is not perception, but judgement
Socrates claims that features (like being, likeness) that apply to multiple sensory modalities cannot

Hume's 'mental geography'
Hume aims to find those principles, which regulate our understanding, excite our sentiments, and
make us approve or blame any particular object, action, or behaviour.
From wax to aviaries
The wax model limited false judgments to the connecting of perception with thought.
Objection: There are also false non-perceptual judgments too (e.g. miscalculations).
A new analogy: A man with an aviary possess

Against the argument from design
Hume attacks the claim that the nature of the universe shows its cause was a perfect, just God:
1. When we infer a cause from an effect, the only qualities we can attribute to the cause are the

Hume claims: even after we have experience of the operations of cause and effect, our
conclusions from that experience are not founded on reasoning, or any process of the

Argument by direction of explanation

One way to reconstruct the argument:
