Gottfried Wilhelm Leibnitz (1646 - 1716), a.k.a. Leibniz, was a 17th/18th Century German mathematician and philosopher, one of the inventors of calculus (the other was Newton; see https://www.maths.tcd.ie/pub/HistMath/People/Leibniz/RouseBall/RB_Leibnitz.html for an interesting article on that).
He also had an influence on psychology. That is because Aristotle (and Thomas Aquinas, etc) claimed there was nothing in the mind that was not first in the senses. Leibnitz added to it, “except for the mind itself”.
