“This bounded terminal speed will be called the maximum that such a heavy body can naturally attain through the air”

Dialogues and Mathematical Demonstrations Concerning Two New Sciences (1638)
Context: The speed of the ball—thanks to opposition from the air—will not go on increasing forever. Rather, what will happen is seen in bodies of very little weight falling through no great distance; I mean, a reduction to equable motion, which will occur also in a lead or iron ball after the descent of some thousands of braccia. This bounded terminal speed will be called the maximum that such a heavy body can naturally attain through the air...

these directions making between them meaningful angles, and senses, together defining one big conclusion or many. Spaces, volumes, suggested by the smallest means in contrast to their mass, or even including them, juxtaposed, pierced by vectors, crossed by speeds. Nothing at all of this is fixed. Each element able to move, to stir, to oscillate, to come and go in its relationships with the other elements in its universe. It must not be just a fleeting moment but a physical bond between the varying events in life. Not extractions, but abstractions. Abstractions that are like nothing in life except in their manner of reacting.

Auxiliaries to the Perception of Intelligible Natures
Context: The soul is bound to the body by a conversion to the corporeal passions; and again liberated by becoming impassive to the body.
That which nature binds, nature also dissolves: and that which the soul binds, the soul likewise dissolves. Nature, indeed, bound the body to the soul; but the soul binds herself to the body. Nature, therefore, liberates the body from the soul; but the soul liberates herself from the body.
Hence there is a twofold death; the one, indeed, universally known, in which the body is liberated from the soul; but the other peculiar to philosophers, in which the soul is liberated from the body. Nor does the one entirely follow the other.
We do not understand similarly in all things, but in a manner adapted to the essence of each. For intellectual objects we understand intellectually; but those that pertain to soul rationally. We apprehend plants spermatically; but bodies idolically (i. e., as images); and that which is above all these, super-intellectually and super-essentially.

Context: Only through the group, I realised — through sharing the suffering of the group — could the body reach that height of existence that the individual alone could never attain. And for the body to reach that level at which the divine might be glimpsed, a dissolution of individuality was necessary. The tragic quality of the group was also necessary, the quality that constantly raised the group out of the abandon and torpor into which it was prone to lapse, leading it to an ever-mounting shared suffering and so to death, which was the ultimate suffering. The group must be open to death — which meant, of course, that it must be a community of warriors.
