| 8000 | He who is ignorant of the history of philosophy is doomed to repeat it [Santayana, by MacIntyre] |
| Full Idea: Santayana remarked that he who is ignorant of the history of philosophy is doomed to repeat it. | |
| From: report of George Santayana (The Life of Reason [1906]) by Alasdair MacIntyre - A Short History of Ethics Ch.1 | |
| A reaction: Santayana's remark seems to have been about history in general, so this is a Macintyre thought. It obviously has a lot of truth, and most great philosophers seem hugely knowledgeable. However, ignorance brings a kind of freedom. |
| 18491 | The idea of 'making' can be mere conceptual explanation (like 'because') [Künne] |
| Full Idea: If we say 'being a child of our parent's sibling makes him your first cousin', that can be paraphrased using 'because', and this is the 'because' of conceptual explanation: the second part elucidates the sense of the first part. | |
| From: Wolfgang Künne (Conceptions of Truth [2003], 3.5.2) | |
| A reaction: Fans of truth-making are certainly made uncomfortable by talk of 'what makes this a good painting' or 'this made my day'. They need a bit more sharpness to the concept of 'making' a truth. |
| 18521 | The criterion of existence is the possibility of action [Santayana] |
| Full Idea: The possibility of action ...is the criterion of existence, and the test of substantiality. | |
| From: George Santayana (The Realm of Matter [1930], p.107), quoted by John Heil - The Universe as We Find It | |
| A reaction: I rather like this. I think I would say the power is the criterion of existence. |
| 23060 | The good is not relative, but is rooted in facts about human needs [Santayana] |
| Full Idea: The good is by no means relative to opinion, but is rooted in the unconscious and fatal nature of living beings, a nature which predetermines for them the difference between foods and poisons, happiness and misery. | |
| From: George Santayana (Platonism and the Spiritual Life [1927], p.3), quoted by John Gray - Seven Types of Atheism 6 | |
| A reaction: That is, he concedes that the good is relative to human beings, but that the relevant facts about human beings are not relative. I think he has the correct picture. The key point is that the good is 'rooted' in something, and doesn't just float free. |
| 6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
| Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
| From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
| A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
