As the ego cogito, subjectivity is the consciousness that represents something, relates this representation back to itself, and so gathers with itself.
Martin HeideggerTeaching is more difficult than learning because what teaching calls for is this: to let learn. The real teacher, in fact, lets nothing else be learned than learning. His conduct, therefore, often produces the impression that we properly learn nothing from him, if by "learning" we now suddenly understand merely the procurement of useful information.
