The magic of Asclepius enters Renaissance thought mixed into Ficino's neo-platonism [Yates]
|
|
Full Idea:
The magic of Asclepius, reinterpreted through Plotinus, enters with Ficino's De Vita into the neo-platonic philosophy of the Renaissance, and, moreover, into Ficino's Christian Platonism.

From:
Frances A. Yates (Giordano Bruno and Hermetic Tradition [1964], Ch.4)
|
|
A reaction:
Asclepius is the source of 'Hermetic' philosophy. This move seems to be what gives the Renaissance period its rather quirky and distinctive character. Montaigne was not a typical figure. Most of them wanted to become gods and control the stars!

The dating, in 1614, of the Hermetic writings as post-Christian is the end of the Renaissance [Yates]
|
|
Full Idea:
The dating by Isaac Casaubon in 1614 of the Hermetic writings as not the work of a very ancient Egyptian priest but written in post-Christian times, is a watershed separating the Renaissance world from the modern world.

From:
Frances A. Yates (Giordano Bruno and Hermetic Tradition [1964], Ch.21)
|
|
A reaction:
I tend to place the end of the Renaissance with the arrival of the telescope in 1610, so the two dates coincide. Simply, magic was replaced by science. Religion ran alongside, gasping for breath. Mathematics was freed from numerology.

Cantor needed Power Set for the reals, but then couldn't count the new collections [Cantor, by Lavine]
|
|
Full Idea:
Cantor grafted the Power Set axiom onto his theory when he needed it to incorporate the real numbers, ...but his theory was supposed to be theory of collections that can be counted, but he didn't know how to count the new collections.
|
|
From:
report of George Cantor (The Theory of Transfinite Numbers [1897]) by Shaughan Lavine - Understanding the Infinite I
|
|
A reaction:
I take this to refer to the countability of the sets, rather than the members of the sets. Lavine notes that counting was Cantor's key principle, but he now had to abandon it. Zermelo came to the rescue.

Freud and others have shown that we don't know our own beliefs, feelings, motive and attitudes [Freud, by Shoemaker]
|
|
Full Idea:
Freud persuaded many that beliefs, wishes and feelings are sometimes unconscious, and even sceptics about Freud acknowledge that there is self-deception about motive and attitudes.
|
|
From:
report of Sigmund Freud (works [1900]) by Sydney Shoemaker - Introspection p.396
|
|
A reaction:
This seems to me obviously correct. The traditional notion is that the consciousness is the mind, but now it seems obvious that consciousness is only one part of the mind, and maybe even a peripheral (epiphenomenal) part of it.
