A few years ago Cambridge University put on line Newton’s notebooks. One ( Trinty College notebook) was interesting in that parts of it were written in Greek.
As it says in their site
“This is a notebook Newton acquired while he was an undergraduate at Trinity College and used from about 1661 to 1665 (see his inscription). It includes many notes from his studies and, increasingly, his own explorations into mathematics, physics and metaphysics. ”
At the beginning he has some definitions. For example the following.
συμβεβηκὸς ἐστίν, ὃ γίνεται καὶ ἀπογίνεται, χωρὶς τῆς τοῦ ὑποκειμένου φθορᾶς
An accident is what a thing becomes or ceases to be without the destruction of its underlying essence.
An accident here means a property or attribute separate from its definition.
When I read this I thought what a clever chap Newton was to philosophise in Greek as well as lay the foundations for modern science. However a bit of research showed that this was not an original thought but he must have noted it as part of his studies. The definition is to be found in
In Porphyrii Isagogen et Aristotelis Categorias commentaria
By Elias (Philosophus)
From Elias the philosopher
Although not an original thought of Newton, I think this is of great interest as it shows that Newton’s education, as was all education then, based on the classics and that part of his scientific education was based on Aristotle and obscure (at least to me!) commentaries on Aristotle. Nowadays there is thought to be a gulf between the arts as exemplified by classics and science but this shows that classics provided the bedrock for modern day science.
