This sounds a lot like the apocryphal Einstein quote
> Everything should be made as simple as possible, but not simpler.
And I found a similar quote from Aquinas
> If a thing can be done adequately by means of one, it is superfluous to do it by means of several; for we observe that nature does not employ two instruments where one suffices

(Aquinas, [BW], p. 129).
