Kantian transcendental apperception, in philosophy, is what Immanuel Kant believes makes experience possible. It is where the self and the world come together. There are six steps to transcendental apperception:

1. All experience is the succession of a variety of contents (this is from David Hume).
2. To be experienced at all, the successive data must be combined, or held together, in a unity for consciousness.
3. Unity of experience therefore implies a unity of self.
4. The unity of self is as much an object of experience as anything is.
5. Therefore experience of both the self and its objects rests on acts of synthesis which, because they are the conditions of any experience, are not themselves experienced.
6. These prior syntheses are made possible by the categories. Categories allow us to synthesize the self and the objects.
