Prompted by the current discussion about Kant’s concept of causality of freedom http://philosophy.stackexchange.com/questions/28746/can-free-will-exist-in-a-causal-material-worldCan Free Will Exist In A Causal Material World? I would like to understand the scope and the difference of the two Kantian concepts
- Freedom as a transcendental idea
- Freedom in its practical sense.
See Critique of Pure Reason (CPR), B561ff. Currently, I understand these two concepts as follows:
An idea is a transcendental idea if it refers to our way to create experience – but not to experience itself. In particular, a transcendental idea lives on the meta-level, it belongs to epistemology.
A concept is practical if it has a normative component, i.e. when the concept considers what should be done. In particular, a practical concepts belongs to ethics.
If you can confirm my understanding of these two concepts, I would like to know – according to Kant
- Why do we need freedom as a transcendental idea?
- Why does freedom in its practical sense explain our experience?
Note. I would wellcome a direct answer, not an invitation to a tour de force through the secondary literature :-)
