9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects
14797 Vagueness is a neglected but important part of mathematical thought [Peirce]
     Full Idea: Logicians have too much neglected the study of vagueness, not suspecting the important part it plays in mathematical thought. It is the antithetical analogue of generality.
     From: Charles Sanders Peirce (Critical Common-Sensism [1905], I)
14798 All communication is vague, and is outside the principle of non-contradiction [Peirce]
     Full Idea: The 'vague' might be defined as that to which the principle of contradiction does not apply. For it is false neither that an animal (in a vague sense) is male, nor that an animal is female. No communication between persons can be entirely non-vague.
     From: Charles Sanders Peirce (Critical Common-Sensism [1905], I)
     A reaction: Note that he makes vagueness largely a matter of the way we talk, which is David Lewis's approach, and looks right to me.
9. Objects / E. Objects over Time / 10. Beginning of an Object
16706 Generation is when local motions aggregate to become a single subject [Nicholas of Autrecourt]
     Full Idea: In the case of natural things there is only local motion. When from such motion there follows an aggregation of natural bodies that are gathered to one another and acquire the nature of a single subject, this is called generation.
     From: Nicholas of Autrecourt (Tractatus [1335], Ch. 1)
     A reaction: This is explosive atomistic corpuscularianism, three centuries before its appointed date. He was duly suppressed. Can he give an account of the 'nature of a single subject' in this way?
22. Metaethics / B. Value / 2. Values / f. Altruism
1590 The just man does not harm his enemies, but benefits everyone [Plato]
     Full Idea: First, Socrates, you told me justice is harming your enemies and helping your friends. But later it seemed that the just man, since everything he does is for someone's benefit, never harms anyone.
     From: Plato (Clitophon [c.372 BCE], 410b)
     A reaction: Socrates certainly didn't subscribe to the first view, which is the traditional consensus in Greek culture. In general Socrates agreed with the views later promoted by Jesus.
