5 ideas
| 4312 | To understand a phenomenon, we must understand why it is necessary, not merely contingent [Spinoza, by Cottingham] |
| Full Idea: Adequate understanding of a phenomenon, for Spinoza, involves a complete understanding of its causes, and this in turn involves a dissolving of the illusion of contingency and a recognition of the necessity of its being thus and not otherwise. | |
| From: report of Baruch de Spinoza (The Ethics [1675]) by John Cottingham - The Rationalists p.168 | |
| A reaction: This is the appeal of the rationalist dream. We want a god-like grasp of things, not a superficial perception of what seems to be going on. |
| 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. |
| 14790 | 'Abduction' is beginning a hypothesis, particularly if it includes preference of one explanation over others [Peirce] |
| Full Idea: The first starting of a hypothesis and the entertaining of it …is an inferential step which I propose to call 'abduction'. This will include a preference for any one hypothesis over others which would equally explain the facts. | |
| From: Charles Sanders Peirce (Abduction and Induction [1901], I) | |
| A reaction: I take there to be no more important function within human thought than the procedure by which we give preference to one particular explanation. It only makes sense, I think, if we take it as part of a coherence theory of justification. |
| 14791 | Abduction involves original suggestions, and not just the testing involved in induction [Peirce] |
| Full Idea: It is of the nature of abduction to involve an original suggestion; while typical induction has no originality in it, but only tests a suggestion already made. | |
| From: Charles Sanders Peirce (Abduction and Induction [1901], I) | |
| A reaction: Peirce's 'abduction' is not, then, just the choice of a best explanation. He came up with the idea because he was keen to capture the creative and imaginative character of rational thought. |
| 19222 | Men often answer inner 'whys' by treating unconscious instincts as if they were reasons [Peirce] |
| Full Idea: Men many times fancy that they act from reason, when the reasons they attribute to themselves are nothing but excuses which unconscious instinct invents to satisfy the teasing 'whys' of the ego. | |
| From: Charles Sanders Peirce (Reasoning and the Logic of Things [1898], I) | |
| A reaction: A strikely modern thought, supported by a lot of modern neuro-science and psychology. It is crucial to realise that we don't have to accept the best explanation we can think of. |
