8886 | Being a true justified belief is not a sufficient condition for knowledge [Gettier] |
Full Idea: The claim that someone knows a proposition if it is true, it is believed, and the person is justified in their belief is false, in that the conditions do not state a sufficient condition for the claim. | |
From: Edmund L. Gettier (Is Justified True Belief Knowledge? [1963], p.145) | |
A reaction: This is the beginning of the famous Gettier Problem, which has motivated most epistemology for the last forty years. Gettier implies that justification is necessary, even if it is not sufficient. He gives two counterexamples. |
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. |
20436 | Art leads to mental health, and mental clarity [Beardsley,M, by Carroll,N] |
Full Idea: Beardsley says aesthetic experience relieves tensions and quiet destructive emotions. It also aids us in sorting out the jumble in the flow of consciousness, by virtue of its tendencies toward heightened clarity and coherence. | |
From: report of Monroe Beardsley (Aesthetics: problems in the philosophy of criticism [1958]) by Noël Carroll - Monroe Beardsley p.162-3 | |
A reaction: I find this claim highly implausible. I like art, but I feel neither healthier nor clearer after experiencing it. |
