Things have real essences, but we categorise them according to the ideas we receive [Locke]
|
|
Full Idea:
This I do say, that there are real constitutions in things from whence simple ideas flow, which we observe combin'd in them. But we distinguish particular substances into sorts or genera not by real essences or constitutions, but by observed simple ideas.

From:
John Locke (Letters to William Molyneux [1692], 1693.01.20)
|
|
A reaction:
This is the clearest statement I can find of Locke's position on essences. He is totally committed to their reality, but strongly aware of the empirical constraints which keep us from direct knowledge of them. He would be amazed by modern discoveries.

Soul must be immortal, since it continually moves, like the heavens [Alcmaeon, by Aristotle]
|
|
Full Idea:
Alcmaeon says that the soul is immortal because it resembles immortal things and that this affection belongs to it because it is always in movement, like divine things, such the moon, the sun, the stars and the whole heaven.
|
|
From:
report of Alcmaeon (fragments/reports [c.490 BCE], DK 24) by Aristotle - De Anima 405a30
|
|
A reaction:
Hm. Fish and rivers seem to be continually moving too. Presumably we are like gods, but then Greek gods seem awfully like humans. I don't know the history of belief in immortality; an interesting topic.
