10 ideas
1597 | Thales was the first western thinker to believe the arché was intelligible [Roochnik on Thales] |
Full Idea: Thales was the first thinker in the west to believe that the arché (the basis of things) was intelligible. | |
From: comment on Thales (fragments/reports [c.585 BCE]) by David Roochnik - The Tragedy of Reason p.138 |
4037 | Ockham's Razor is the principle that we need reasons to believe in entities [Mellor/Oliver] |
Full Idea: Ockham's Razor is the principle that we need reasons to believe in entities. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §9) | |
A reaction: This presumably follows from an assumption that all beliefs need reasons, but is that the case? The Principle of Sufficient Reason precedes Ockham's Razor. |
4027 | Properties are respects in which particular objects may be alike or differ [Mellor/Oliver] |
Full Idea: Properties are respects in which particular objects may be alike or differ. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §1) | |
A reaction: Note that this definition does not mention a causal role for properties. |
4029 | Nominalists ask why we should postulate properties at all [Mellor/Oliver] |
Full Idea: Nominalists ask why we should postulate properties at all. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §3) | |
A reaction: Objects might be grasped without language, but events cannot be understood, and explanations of events seem inconceivable without properties (implying that they are essentially causal). |
3013 | Nothing is stronger than necessity, which rules everything [Thales, by Diog. Laertius] |
Full Idea: Necessity is the strongest of things, for it rules everything. | |
From: report of Thales (fragments/reports [c.585 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 01.2.9 |
4039 | Abstractions lack causes, effects and spatio-temporal locations [Mellor/Oliver] |
Full Idea: Abstract entities (such as sets) are usually understood as lacking causes, effects, and spatio-temporal location. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §10) | |
A reaction: This seems to beg some questions. Has the ideal of 'honour' never caused anything? Young men dream of pure velocity. |
1494 | Thales said water is the first principle, perhaps from observing that food is moist [Thales, by Aristotle] |
Full Idea: Thales says water is the first principle (which is why he declared the earth is on water); perhaps he concluded this from seeing that all food is moist. | |
From: report of Thales (fragments/reports [c.585 BCE], A12) by Aristotle - Metaphysics 983b12 |
1713 | Thales must have thought soul causes movement, since he thought magnets have soul [Thales, by Aristotle] |
Full Idea: Thales seems, from what is recorded of him, to have supposed that the soul is something productive of movement, if he really said that the magnet has soul because it produces movement in iron. | |
From: report of Thales (fragments/reports [c.585 BCE]) by Aristotle - De Anima 405a20 |
1742 | Thales said the gods know our wrong thoughts as well as our evil actions [Thales, by Diog. Laertius] |
Full Idea: When asked whether a man who did wrong could escape the notice of the gods, Thales is said to have replied: 'No, not even if he thinks wrong.' | |
From: report of Thales (fragments/reports [c.585 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 01.Th.9 |
1513 | The Egyptians were the first to say the soul is immortal and reincarnated [Herodotus] |

From: Herodotus (The Histories [c.435 BCE], 2.123.2) |
