21397 | Perception an open hand, a fist is 'grasping', and holding that fist is knowledge [Zeno of Citium, by Long] |
Full Idea: Zeno said perceptions starts like an open hand; then the assent by our governing-principle is partly closing the hand; then full 'grasping' is like making a fist; and finally knowledge is grasping the fist with the other hand. | |
From: report of Zeno (Citium) (fragments/reports [c.294 BCE]) by A.A. Long - Hellenistic Philosophy 4.3.1 | |
A reaction: [In Cicero, Acad 2.145] It sounds as if full knowledge requires meta-cognition - knowing that you know. |
4266 | Having beliefs involves recognition, expectation and surprise [Scruton] |
Full Idea: With the concept of belief (e.g. in animals) comes recognition, expectation and surprise. | |
From: Roger Scruton (Animal Rights and Wrongs [1996], p.15) | |
A reaction: A good observation. It is always tempting to see mental faculties in isolation, but each one drags along other capacities with it. Looks a bit holistic. |
4265 | If an animal has beliefs, that implies not only that it can make mistakes, but that it can learn from them [Scruton] |
Full Idea: To say that an animal has beliefs is to imply not just that it can make mistakes, but also that it can learn from them. | |
From: Roger Scruton (Animal Rights and Wrongs [1996], p.15) | |
A reaction: A bold claim which is hard to substantiate. Seems right, though. Why would they change a belief? It can't be a belief if it isn't changeable. That would be an instinct. |
20799 | A grasp by the senses is true, because it leaves nothing out, and so nature endorses it [Zeno of Citium, by Cicero] |
Full Idea: He thought that a grasp made by the senses was true and reliable, …because it left out nothing about the object that could be grasped, and because nature had provided this grasp as a standard of knowledge, and a basis for understanding nature itself. | |
From: report of Zeno (Citium) (fragments/reports [c.294 BCE]) by M. Tullius Cicero - Academica I.42 | |
A reaction: Sounds like Williamson's 'knowledge first' claim - that the basic epistemic state is knowledge, which we have when everything is working normally. I like Zeno's idea that a 'grasp' leaves nothing out about the object. Compare nature with Descartes' God. |
