Cf. Aquinas (1225-1274), Summa Theologica I,2,3: 'Therefore, whatever is moved is moved by another. If that by which it is moved be itself moved then this also must needs be moved by another, and that by another again. But this cannot go on to infinity, because there would be no first mover, and consequently no other mover…Therefore it is necessary to arrive at a first mover moved by no other, and this everyone understands to be God.' [Aquinas’ 'First Way' or first proof of the existence of God]
