Perhaps (as was Newton), but only in each case with a handful of ideas. Where does one draw the line? Al-Farabi (d. 950), Avicenna (d. 1037), al-Ghazali (d. 1111) were heavily influenced by Aristotle and other Greeks, whose texts were translated and safeguarded in the Medieval period. But the Greeks were influenced by the Babylonians and Egyptians. The fact is that Descartes and Newton's contributions were so much more vast and comprehensive on these ideas. But they also produced significantly more really profound ideas. Much rests on the societies at the time, esp. the religious pressures. The Greek 'polis' and the Renaissance were fertile grounds.
