Educational theorists working within the tradition of Jacques Derrida and Emmanuel Levinas's thought, posit teaching to be a site of implied ethics, that is, a realm in which non-violent or less violent relations to the other are possible. Derrida links ethics to the realm of friendship, enabling one to understand teaching as a site of the ethics of friendship. I clarify how friendship, as a re-metaphorization of differance, opens us up to a conception of teaching that provides a counterpoint to the current discourse of 'effective' teaching. I draw out the implications of the Derridean conception of friendship for the educator in his or her philosophical orientation towards teaching and attempt to show that friendship points the educator towards an orientation that enables a "fine tuning" and opening up of one's sense of obligation and responsibility to one's students in ways that cannot be circumscribed to current or institutionally sanctioned ways of understanding the activity of teaching, especially as it is often envisioned in American public education.
