In this article, we argue that it is possible to approach teaching from a fully affirmative perspective: as an educational practice that has its own internal logic and intrinsic value. By analysing a fragment from one of the Leonard Bernstein's Young People's Concerts presented in this article as a teaching event, we show that when starting from an empirical example of teaching it is possible to distinguish principles and gestures that testify to an ontological dimension of teaching. This is possible, however, only when a particular reading of this empirical material is applied. We call this an immanent reading, as opposed to a transcendent (in this case critical) reading. It should be clear that this kind of inquiry we briefly demonstrate here is exactly a post-critical attempt to re-establish our affirmative relation with one of the most devalued, repressed, and neglected educational practice, namely teaching.
