Smith, educated at Oundle School, entered Emmanuel College, Cambridge, in 1636, took his B.A. in 1640 and his M.A. in 1644, at which time he was chosen fellow of Queens' College.^[2] His health seems to have been precarious from the first. His labours were principally confined to his office as teacher, for which he had remarkable qualifications. His preaching was with a rare degree of eloquence, which can still be felt in the Select Discourses (1660). In that work, he writes about several metaphysical and epistemological issues surrounding Christianity — the existence of God, eternal life and rationality. He gained much local fame as a lecturer on mathematics. His personal character was such as to excite the admiration of his associates to a remarkable degree. As a "founder" of the Cambridge Platonists, his special service was in developing a Christian philosophy that was deeply rational and open to the new science yet directed to the practical goal of living a religious life. To these ends, Smith drew heavily from Plotinus.
