| 23950 | Freud said passions are pressures of some flowing hydraulic quantity [Freud, by Solomon] |
| Full Idea: Freud argued that the passions in general …were the pressures of a yet unknown 'quantity' (which he simply designated 'Q'). He first thought this flowed through neurones, …and always couched the idea in the language of hydraulics. | |
| From: report of Sigmund Freud (works [1900]) by Robert C. Solomon - The Passions 3.4 | |
| A reaction: This is the main target of Solomon's criticism, because its imagery has become so widespread. It leads to talk of suppressing emotions, or sublimating them. However, it is not too different from Nietzsche's 'drives' or 'will to power'. |
| 9789 | You can't abstract natural properties to make Forms - objects and attributes are defined together [Aristotle] |
| Full Idea: Those who say there are Forms abstract natural properties, even though they are less separable than mathematical properties. This is clear if you try to define both the objects themselves and their attributes. | |
| From: Aristotle (Physics [c.337 BCE], 193b36) | |
| A reaction: (Compare Idea 9788) This is Frege's black and white cats, where you cannot abstract the black without thinking of the cat, but Aristotle thinks mathematical abstraction is more feasible. |
| 9788 | Mathematicians study what is conceptually separable, and doesn't lead to error [Aristotle] |
| Full Idea: Mathematicians abstract properties which are conceptually separable from the world of change. It makes no difference if you treat them as separate, in the sense that it does not result in error. | |
| From: Aristotle (Physics [c.337 BCE], 193b33) | |
| A reaction: This strikes me as a crucial point to make against Frege (if Aristotle is right). Frege hates abstractionism precisely because it is psychological, and hence admits subjective error, instead of objective truth. Does 'pure' abstraction avoid error? |
