Not-Being obviously doesn't exist, and the five modes of Being are all impossible [Gorgias, by Diog. Laertius]
|
|
Full Idea:
I. Nothing exists. a) Not-Being does not exist. b) Being does not exist as everlasting, as created, as both, as One, or as Many. II. If anything does exist, it is incomprehensible. III. If existence is comprehensible, it is incommunicable.

From:
report of Gorgias (fragments/reports [c.443 BCE], B03) by Diogenes Laertius - Lives of Eminent Philosophers 09

|
A reaction:
[Also Sextus Empiricus, Against Logicians I.65-] For Part I he works through all the possible modes of being he can think of, and explains why none of them are possible. It is worth remembering that Gorgias loved rhetoric, not philosophy!

The concept of mind excludes body, and vice versa [Descartes]
|
|
Full Idea:
The concept of body includes nothing at all which belongs to the mind, and the concept of mind includes nothing at all which belongs to the body.
|
|
From:
René Descartes (Reply to Fourth Objections [1641], 225)
|
|
A reaction:
A headache? Hunger? The mistake, I think, is to regard the mind as entirely conscious, thus creating a sharp boundary between two aspects of our lives. As shown by blindsight, I take many of my central mental operations to be pre- or non-conscious.

Gorgias says rhetoric is the best of arts, because it enslaves without using force [Gorgias, by Plato]
|
|
Full Idea:
Gorgias insists that the art of persuasion is superior to all others because it enslaves all the rest, with their own consent, not by force, and is therefore by far the best of all the arts.
|
|
From:
report of Gorgias (fragments/reports [c.443 BCE]) by Plato - Philebus 58a
|
|
A reaction:
A nice point, and it is not unreasonable to rank the arts in order of their power. To enchant, without achieving agreement, and to speak truth without persuading, are both very fine, but there is something about success that cannot be gainsaid.
