Connecting Nicholas of Cusa, Gottfried Leibniz, and the Founders of the USA to Jesus Christ and Greek Thinking in 500 B.C.
Give Anaxagoras credit for developing the idea of Parmenides who said "All is One." (click) The 'All in One' idea is repeated by Jesus Christ in John 14:20 as '".. I am in the Father, and ye in me, and I in you." In Bk.II, Ch. Five of his book 'On Learned Ignorance,' Nicholas of Cusa expands the 'All in One' idea with the words 'Each thing is in each thing' and the words "From Book One it is evident that God is in all things in a such way that all things are in Him." If each thing in the universe is divisible and originate from an indivisible God, each thing in the universe has an infinite number of indivisible parts.
I am unable to connect Cusa directly to Gottrried Leibniz (1646-1716). However, I conclude that Leibniz could have learned about Cusa's indivisibles through the thinking of Galileo, who knew about Cusa's work. Anyway, Cusa's indivisibles are found in Leibniz's New System, which opposes Newton's billiard ball universe. In No.56 of Leibniz's Monadology, he says that every thing is connected to alll other things. Cusa's indivisibles are also found in Leibniz's infinitesimal calculus and the true atom defined in his book on 'Monadology.' The use of Cusa's indivisibles are found by Galileo;s thoughts on the extension of bodies. These connections set the stage for the development of functional relations in the field of mathematics.
In closing, I noticed that Immanuel Kant shows his sensitive to the '"All in One" idea in his "Critique of Pure Reason' in the Preface to Second Edition. There, Kant talks about 'organized bodies' sayings, "... every member exists for every other, and all for the sake of each other, so that no principle can safely be taken in any one relation, unless it has been investigated in the entirety of its relations to the whole employment of pure reason."
