According to Wikipedia, Aristotle may have favored something like Occam's razor:
Aristotle writes in his Posterior Analytics, "We may assume the superiority ceteris paribus [other things being equal] of the demonstration which derives from fewer postulates or hypotheses."
Based on that, a search on the Internet Archive found this in Posterior Analytics: (page 147)
It may be assumed that, given the same conditions, that form of demonstration is superior to the rest which depends upon fewer postulates or hypotheses or premisses...
The Wikipedia article surveys various positions related to Occam's razor and even mentions "anti-razors" presented by Leibniz and Kant.
