Anecdote (1701) from John Conduitt's manuscript, as quoted by Sir David Brewster, Memoirs of the Life, Writings, and Discoveries of Sir Isaac Newton (1855) Vol.2 https://books.google.com/books?id=Bp8RAAAAYAAJ
“The predecessors of Newton and Leibnitz knew perfectly well how to determine tangents and areas, but they had to approach each problem from first principles. The great contribution of Newton and Leibnitz was precisely to make the procedures for finding tangents, areas, etc. into a calculus, that is, a systematic way of calculating—a collection of algorithms, to use the currently fashionable word.”
