“All Taliban are moderate. There are two things: extremism ["ifraat", or doing something to excess] and conservatism ["tafreet", or doing something insufficiently]. So in that sense, we are all moderates - taking the middle path.”

Context: As there must be moderation in other things, so there must be moderation in self-criticism. Perpetual contemplation of our own actions produces a morbid consciousness, quite unlike that normal consciousness accompanying right actions spontaneously done; and from a state of unstable equilibrium long maintained by effort, there is apt to be a fall towards stable equilibrium, in which the primitive nature reasserts itself. Retrogression rather than progression may hence result.
