6294 | In the beginning was the Word, and the Word was with God, and the word was God [John] |
Full Idea: In the beginning was the Word, and the Word was with God, and the word was God. | |
From: St John (04: Gospel of St John [c.95], 01.01) | |
A reaction: 'Word' translates the Greek word 'logos', which has come a long way since Heraclitus. The interesting contrast is with the later Platonist view that the essence of God is the Good. So is the source of everything to be found in reason, or in value? |
8821 | Jesus said he bore witness to the truth. Pilate asked, What is truth? [John] |
Full Idea: Jesus: I came into the world, that I should bear witness unto the truth. Everyone that is of the truth heareth my voice. Pilate saith unto him, What is truth? | |
From: St John (04: Gospel of St John [c.95], 18:37-8) | |
A reaction: There is very little explicit discussion of truth in philosophy before this exchange (apart from Ideas 251 and 586), and there isn't any real debate prior to Russell and the pragmatists. What was Pilate's tone? Did he spit at the end of his question? |
16740 | A power is not a cause, but an aptitude for a cause [Zabarella] |
Full Idea: A power is not the cause of an operation, but only the cause's aptitude for operating. | |
From: Jacob Zabarella (De rebus naturalibus [1590], De fac anim 4:col 692), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.5 | |
A reaction: His example is the power of running, which is actually caused by the soul (or whatever), which generates the power. A power is a very superficial thing. |
23633 | Many truths seem obvious, and point to universal agreement - which is what we find [Reid] |
Full Idea: There are many truths so obvious to the human faculties, that it should be expected that men should universally agree in them. And this is actually found to be the case with regard to many truths, against which we find no dissent. | |
From: Thomas Reid (Essays on Intellectual Powers 1: Preliminary [1785], 2) | |
A reaction: He says that a few sceptical philosophers may disagree. This is a nice statement of his creed of common sense. I agree with him, and Aristotle observes the same fact. |
23630 | Only philosophers treat ideas as objects [Reid] |
Full Idea: The vulgar allow that an 'idea' implies a mind that thinks, an act of mind which we call thinking, and an object about which we think. But the philosopher conceives a fourth - the idea, which is the immediate object. …I believe this to be a mere fiction. | |
From: Thomas Reid (Essays on Intellectual Powers 1: Preliminary [1785], 1) | |
A reaction: Another example, to add to Yablo's list, of abstract objects invented by philosophers to fill holes in their theories. This one is illuminating, because we all say 'I've got an idea'. Cf discussions of the redundancy of truth. Cf propositions. |
23629 | The ambiguity of words impedes the advancement of knowledge [Reid] |
Full Idea: There is no greater impediment to the advancement of knowledge than the ambiguity of words. | |
From: Thomas Reid (Essays on Intellectual Powers 1: Preliminary [1785], 1) | |
A reaction: He means that ambiguity leads to long pointless disagreements. |
16571 | Prime matter is exceptionally obscure [Zabarella] |
Full Idea: Nothing in the natural world seems to be more obscure and difficult to grasp than the prime matter of things. | |
From: Jacob Zabarella (De rebus naturalibus [1590], I.1 col 133), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 2.1 | |
A reaction: This spells the beginning of the end for 'prime matter', since a late scholastic is doubting it, even before the scientists got to work. Most modern Aristotelians slide quietly past prime matter, as unhelpful. |
23632 | Similar effects come from similar causes, and causes are only what are sufficient for the effects [Reid] |
Full Idea: A first principle is that similar effects proceed from the same or similar causes; that we ought to admit of no other causes …but such as are sufficient to account for the effects. | |
From: Thomas Reid (Essays on Intellectual Powers 1: Preliminary [1785], 2) | |
A reaction: He treats these as a priori axioms of natural philosophy. In evolution similar causes seem to produce startlingly divergent effects, such as the mating needs of male birds. |
