| 15381 | Dyamic logics model changes between classical states, in action, belief, and computing [Uckelman] |
| Full Idea: Dynamic logic gives versions of propositional, modal and predicate logics, in which the states are classical, but changes of assignments between states can be expressed, by modelling action, knowledge and belief change, and compute programs. | |
| From: Sara L. Uckelman (Dynamic Logics [2010]) | |
| A reaction: [compressed] |
| 4921 | Quantum states in microtubules could bind brain activity to produce consciousness [Penrose] |
| Full Idea: I propose that microtubules in nerve cells could give rise to a stable quantum state that would bind the activity of brain cells throughout the cerebrum and in doing so give rise to consciousness. | |
| From: Roger Penrose (Could a computer ever understand? [1998], p.329) | |
| A reaction: This seems to offer a physical theory to account for the 'unity' of the mind (which so impressed Descartes), but I don't quite see why being aware of things would ensue from some 'quantum binding'. I daresay 'quantum binding' occurs in the Sun. |
| 20581 | If men are born free, are women born slaves? [Astell] |
| Full Idea: If all men are born free, how is it that all women are born slaves? | |
| From: Mary Astell (A Serious Proposal to the Ladies I [1694]), quoted by Johanna Oksala - Political Philosophy: all that matters Ch.9 | |
| A reaction: What a magnificent question for such an early date. She is said to have been the 'first British feminist'. It is not just a feminist point, but a strong objection to the idea that anyone is 'born free'. Because there is no way to tell if it is true. |
