“Alexander Rostov was neither scientist nor sage; but at the age of sixty-four he was wise enough to know that life does not proceed by leaps and bounds. It unfolds. At any given moment, it is the manifestation of a thousand transitions. Our faculties wax and wane, our experiences accumulate and our opinions evolve--if not glacially, then at least gradually. Such that the events of an average day are as likely to transform who we are as a pinch of pepper is to transform a stew.”
