Chapter
Eighteen: Gottfried LeibnizGottfried Wilhelm Leibniz lived from 1646 to 1716 (thirteen years after the birth of Spinoza and four years before the death of Descartes). He studied geometry under the guidance of Christiaan Huygens and in 1676 Leibniz completed his discovery of Differential Calculus (independently of Sir Isaac Newton). Prior to this discovery of Calculus, Gottfried Leibniz wrote extensively on a number of subjects such as logic, truth, reason, philosophy and metaphysics which culminated in his Monadology. ... His philosophical contribution to metaphysics is based on the Monadology, which introduces Monads as "substantial forms of being", which are akin to spiritual atoms, eternal, indecomposable, individual, following their own laws, not interacting but each reflecting the whole universe in pre-established harmony. According to him the monads are centres of force, and substance is force, while space, matter, and motion are merely phenomenal; finally, the existence of God is inferred from the existing harmony among the monads. ....

I hold that the mark of a genuine idea is that its possibility can be proved, either a priori by conceiving its cause or reason, or a posteriori when experience teaches us that it is in fact in nature. ... It is a good thing to proceed in order and to establish propositions. This is the way to gain ground and to progress with certainty.
Reality cannot be found except in One single source, because of the interconnection of all things with one another. …I do not conceive of any reality at all as without genuine unity. …I maintain also that substances, whether material or immaterial, cannot be conceived in their bare essence without any activity, activity being of the essence of substance in general.
I agree with you that it is important to examine our presuppositions, thoroughly and once for all, in order to establish something solid. For I hold that it is only when we can prove all that we bring forward that we perfectly understand the thing under consideration. I know that the common herd takes little pleasure in these researches, but I know also that the common herd take little pains thoroughly to understand things. ... a distinction must be made between true and false ideas, and that too much rein must not be given to a man's imagination under pretext of its being a clear and distinct intellection.
But it is the knowledge of necessary and eternal truths which distinguishes us from mere animals, and gives us reason and the sciences, raising us to knowledge of ourselves and God. It is this in us which we call the rational soul or mind. (Gottfried Leibniz, Philosophical Writings, 1670)
