6 ideas
| 7493 | Let us reason together, saith the Lord [Isaiah] |
| Full Idea: Come now, and let us reason together, saith the Lord. | |
| From: Isaiah (23: Book of Isaiah [c.680 BCE], 01.18) | |
| A reaction: A verse which not only offers Biblical support for philosophy, but would also seem to be a challenge to Christian fideists. |
| 16541 | All the intrinsic properties of a thing should be deducible from its definition [Spinoza] |
| Full Idea: The definition of a thing should be such that all the properties of that thing, in so far as it is considered by itself, and not in conjunction with other things, can be deduced from it. | |
| From: Baruch de Spinoza (Improvement of Understanding [1675], p.35), quoted by E.J. Lowe - What is the Source of Knowledge of Modal Truths? 6 | |
| A reaction: This is exactly what Locke requires of a real essence (though he is pessimistic about ever achieving it). Spinoza is talking of an Aristotelian real definition, which may be complex, and not a lexicographer's short verbal explication. |
| 13073 | To understand the properties we must know the essence, as with a circle [Spinoza] |
| Full Idea: If a circle is defined as a figure in which lines from centre to circumference are equal, such definitions do not explain the essence of a circle, but only a property. The properties of a thing are not understood as long as their essences are not known. | |
| From: Baruch de Spinoza (Improvement of Understanding [1675], §95), quoted by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz 1.2.1 | |
| A reaction: This is the traditional Aristotelian view of essence, and the example of a circle is nice, though I am not sure what the essence of a circle might be. Presumably ALL the properties of a circle must flow from it. |
| 20959 | Concepts are only analytic once the predicate is absorbed into the subject [Schleiermacher] |
| Full Idea: The difference between analytic and synthetic judgements is an unimportant fluid one. 'Ice melts' is analytic if it is already taken up into the concept of ice, and synthetic if not yet taken up. It is just a different state of the formation of concepts. | |
| From: Friedrich Schleiermacher (Dialektik [1833], p.563), quoted by Andrew Bowie - Introduction to German Philosophy 8 'Scientific' | |
| A reaction: [compressed] I wonder if Quine ever encountered this quotation. The idea refers to Kant's notion of analyticity, and makes the good point that predicates only become 'contained in the subject' once the situation is very familiar. |
| 7608 | The world is established, and cannot be moved [Isaiah] |
| Full Idea: The world is also established, that it cannot be moved. | |
| From: Isaiah (23: Book of Isaiah [c.680 BCE], 93.1) | |
| A reaction: This verse caused big trouble for Galileo. The only reason I can think of for Isaiah to write this is that occasionally people were prone to panic, and worry that the Earth might suddenly and abruptly be moved. |
| 7343 | Beside me there is no God [Isaiah] |
| Full Idea: I am the first, and I am the last; and beside me there is no God. | |
| From: Isaiah (23: Book of Isaiah [c.680 BCE], 44.06) | |
| A reaction: This seems to be the first clear statement (c. 680 BCE) of monotheism, certainly preceding any Greek views on the subject (cf. Idea 2629,Idea 7347). It is not just an arrogant assertion by the jews, but a humble sacrifice, donating their god to humanity. |
