8 ideas
| 4304 | Descartes says there are two substance, Spinoza one, and Leibniz infinitely many [Cottingham] |
| Full Idea: Descartes was a dualist about substance, Spinoza was a monist, and Leibniz was a pluralist (an infinity of substances). | |
| From: John Cottingham (The Rationalists [1988], p.76) | |
| A reaction: Spinoza is appealing. We posit a substance, as the necessary basis for existence, but it is unclear how more than one substance can be differentiated. If mind is a separate substance, why isn't iron? Why aren't numbers? |
| 4303 | The notion of substance lies at the heart of rationalist metaphysics [Cottingham] |
| Full Idea: The notion of substance lies at the heart of rationalist metaphysics. | |
| From: John Cottingham (The Rationalists [1988], p.75) | |
| A reaction: The idea of 'substance' has had an interesting revival in modern philosophy (though not, obviously, in physics). Maybe physics and philosophy have views of reality which are not complementary, but are rivals. |
| 3061 | Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius] |
| Full Idea: Anaxarchus said that he was not even sure that he knew nothing. | |
| From: report of Anaxarchus (fragments/reports [c.340 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.10.1 |
| 4316 | Either all action is rational, or reason dominates, or reason is only concerned with means [Cottingham] |
| Full Idea: We can distinguish rational exclusivism (all activity is guided by reason - Plato and Spinoza), rational hegemonism (all action is dominated by reason), and rational instrumentalism (reason assesses means rather than ends - Hume). | |
| From: John Cottingham (Reason, Emotions and Good Life [2000]) | |
| A reaction: The idea that reason is the only cause of actions seems deeply implausible, but I strongly resist Hume's instrumental approach. Action without desire is not a contradiction. |
| 15675 | We don't condemn people for being bad at reasoning [Finlayson] |
| Full Idea: We do not morally disapprove of people who are incompetent reasoners. | |
| From: James Gordon Finlayson (Habermas [2005], Ch.6:83) | |
| A reaction: Well, we don't morally disapprove simply of their lack of reasoning ability, but we may morally disapprove of their actions, which have arisen entirely from the disability. |
| 15674 | One can universalise good advice, but that doesn't make it an obligation [Finlayson] |
| Full Idea: 'Early to bed and early to rise' is a universalizable maxim, but, though it might be good advice, there is obviously no such obligation. | |
| From: James Gordon Finlayson (Habermas [2005], Ch.6:83) | |
| A reaction: I take it that Kant's rule won't distinguish moral guidance from prudential guidance. Unfair, I think. I may be a lark, but when I universalise this maxim I see that it can't be willed as a universal rule, because we should tolerate the owls. |
| 15662 | The 'culture industry' is an advertisement for the way things are [Finlayson] |
| Full Idea: Critical theory said that culture unwittingly played the role of an advertisement for the way things are. Horkheimer and Adorno referred to this phenomenon as the 'culture industry'. | |
| From: James Gordon Finlayson (Habermas [2005], Ch.1:04) | |
| A reaction: An interesting perspective. However, absolutely everything is an advertisement for what it offers. I think this is especially true of moral (and immoral) actions. |
| 4306 | For rationalists, it is necessary that effects be deducible from their causes [Cottingham] |
| Full Idea: The rationalist view of causation takes it that to make effects intelligible, it must be shown that they are in principle deducible from their causes. | |
| From: John Cottingham (The Rationalists [1988], p.92) | |
| A reaction: This has intuitive appeal, but deduction is only possible with further premises, such as the laws of physics. The effects of human behaviour look a bit tricky, even if we cause them. |
