I would not do so much wrong to Plato, but yet I may truly say with Aristotle, that he too much lost himself in, and too much doted upon that, his Geometry: for that in conclusion these Mathematical subtilties, Salviatus, are true in abstract, but applied to sensible and Physical matter, they hold not good. For the Mathematicians will very well demonstrate for example, that Sphæra tangit planum in puncto [the sphere touches the plane at the point]; a position like to that in dispute, but when one cometh to the matter, things succeed quite another way. And so I may say of these angles of contact, and these proportions; which all evaporate into Air, when they are applied to things material and sensible.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "I would not do so much wrong to Plato, but yet I may truly say with Aristotle, that he too much lost himself in, and too much doted upon that, his Geometry: for that in conclusion these Mathematical subtilties, Salviatus, are true in abstract, but applied to sensible and Physical matter, they hold not good.

And so I may say of these angles of contact, and these proportions; which all evaporate into Air, when they are applied to things material and sensible." in the context of "Galileo Galilei, Dialogue Concerning the Two Chief World Systems (1632) as quoted in the Salusbury translation, The Systeme of the World: in Four Dialogues (1661) Simplicius, p. 181" to mean that wisdom is timeless.
