Teachers need grounded ethical confidence: an intellectual virtue analogous
to courage. I distinguish this from SCAA's notion of teacher confidence, b
ased on the 'authority of consensus'. Such a notion is challenged by Wittge
nstein's later philosophy. I argue that confidence in authority is deferent
ial rather than intellectual, which is not what we want for teachers. As co
urage (according to Aristotle) is a mean between vices, grounded ethical co
nfidence is a mean between tendencies to excessive and insufficient doubt (
forms of 'not knowing one's way about' philosophically.) It is the virtue o
f thinking well ethically, and knowing that one thinks well.
