Auxiliaries to the Perception of Intelligible Natures
Contexto: 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.

Contexto: Soul, indeed, is a certain medium between an impartible essence, and an essence which is divisible about bodies. But intellect is an impartible essence alone. And qualities and material forms are divisible about bodies.
Not everything which acts on another, effects that which it does effect by approximation and contact; but those natures which effect any thing by approximation and contact, use approximation accidentally.

Introduction to Aristotle's Organon, as translated by Octavius Freire Owen (1853), p. v
Contexto: The utility of a science which enables men to take cognizance of the travellers on the mind's highway, and excludes those disorderly interlopers, verbal fallacies, needs but small attestation. Its searching penetration by definition alone, before which even mathematical precision fails, would especially commend it to those whom the abstruseness of the study does not terrify, and who recognise the valuable results which must attend discipline of mind. Like a medicine, though not a panacea for every ill, it has the health of the mind for its aim, but requires the determination of a powerful will to imbibe its nauseating yet wholesome influence: it is no wonder therefore that puny intellects, like weak stomachs, abhor and reject it.
