5988 | Anaximander produced the first philosophy book (and maybe the first book) [Anaximander, by Bodnár] |
Full Idea: Anaximander was the first to produce a philosophical book (later conventionally titled 'On Nature'), if not the first to produce a book at all. | |
From: report of Anaximander (fragments/reports [c.570 BCE]) by István Bodnár - Anaximander | |
A reaction: Wow! Presumably there were Egyptian 'books', but this still sounds like a stupendous claim to fame. |
1496 | The earth is stationary, because it is in the centre, and has no more reason to move one way than another [Anaximander, by Aristotle] |
Full Idea: Something which is established in the centre and has equality in relation to the extremes has no more reason to move up than it has down or to the sides (so the earth is stationary) | |
From: report of Anaximander (fragments/reports [c.570 BCE], A26) by Aristotle - On the Heavens 295b11 |
18470 | Maybe truth-making is an unanalysable primitive, but we can specify principles for it [Smith,B] |
Full Idea: The signs are that truth-making is not analysable in terms of anything more primitive, but we need to be able to say more than just that. So we ought to consider it as specified by principles of truth-making. | |
From: Barry Smith (Truth-maker Realism: response to Gregory [2000], p.20), quoted by Fraser MacBride - Truthmakers 1.5 | |
A reaction: This is the axiomatic approach to such problems - treat the target concept as an undefinable, unanalysable primitive, and then give rules for its connections. Maybe all metaphysics should work like that, with a small bunch of primitives. |
18469 | God might necessitate that something happen, but He is not the truth-maker for it [Smith,B] |
Full Idea: Suppose that God wills that John kiss Mary now. God's willing thereby necessitates the truth of 'John is kissing Mary'. But God's act is not a truth-maker for this judgement. | |
From: Barry Smith (Truth-maker Realism [1999], p.6), quoted by Fraser MacBride - Truthmakers 1.2 | |
A reaction: The point is that truth-making relates to the fact that it happened, not what necessitated it to happen. But Armstrong might reply that his truth-maker 'necessitation' primitive is not the kind of necessitation found in worldly relations. |
13931 | By using aporiai as his start, Aristotle can defer to the wise, as well as to the many [Haslanger] |
Full Idea: The Aristotelian method of working form aporia allows one to use as starting points not only what is said by 'the many', but also what is said by 'the wise', including philosophers. | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 1 n2) | |
A reaction: [She mentions Nussbaum 1986:ch 7 for the opposing view] I like this thought a lot. Aristotle's democratic respect for widespread views can be a bit puzzling sometimes. |
14874 | Anaximander saw the contradiction in the world - that its own qualities destroy it [Anaximander, by Nietzsche] |
Full Idea: Anaximander discovers the contradictory character of our world: it perishes from its own qualities. | |
From: report of Anaximander (fragments/reports [c.570 BCE]) by Friedrich Nietzsche - Unpublished Notebooks 1872-74 19 [239] | |
A reaction: A lovely gloss on Anaximander, though I am not sure that I understand what Nietzsche means. |
13925 | Ontology disputes rest on more basic explanation disputes [Haslanger] |
Full Idea: Disputes over ontology derive from more fundamental disputes over forms of explanation. | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 1) | |
A reaction: It immediately strikes me that Haslanger has stolen my master idea, but unfortunately the dating suggests that she has priority. The tricky part is to combine this view with realism. |
13924 | The persistence of objects seems to be needed if the past is to explain the present [Haslanger] |
Full Idea: The notion that things persist through change is deeply embedded in ideas we have about explanation, and in particular, in the idea that the present is constrained by the past. | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 1) | |
A reaction: I take this to be both an important and an attractive idea. Deniers of persistence (4D-ists) will presumably have some ability to explain the present, but it is the idea of the present being 'constrained' by the past which is a challenge. |
13930 | Persistence makes change and its products intelligible [Haslanger] |
Full Idea: Persistence offers intelligibility: the possibility of understanding a change, and of understanding the products of it. | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 8) | |
A reaction: I think this is exactly right, and it is a powerful idea with wide implications for metaphysics. Haslanger claims that an understanding of 'substance' is needed, which leads towards my defence of essentialism. |
13927 | We must explain change amongst 'momentary entities', or else the world is inexplicable [Haslanger] |
Full Idea: If the world of time-slices is to be explicable, then it must be possible to provide explanations of change understood as a continual generation and destruction of these 'momentary entities'. | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 7) | |
A reaction: While fans of time-slices can offer some sort of explanation, in the process of explaining a 'worm', there don't seem to be the sort of causal chains that we traditionally rely on. Maybe there are no explanations of anything? |
13928 | If the things which exist prior to now are totally distinct, they need not have existed [Haslanger] |
Full Idea: How is the case in which A exists prior to B, but is distinct from B, different (especially from B's point of view) from the case in which nothing exists prior to B? | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 7) | |
A reaction: I sympathise with her view, but this isn't persuasive. For A substitute 'Sally's mother' and for B substitute 'Sally'. A 4D-ist could bite the bullet and say that, indeed, previous parts of my 'worm' need not have existed. |
13929 | Natural explanations give the causal interconnections [Haslanger] |
Full Idea: Natural explanations work by showing the systematic causal interconnections between things. | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 7) | |
A reaction: On the whole I love this sort of idea, but I am wondering if this one prevents mathematical or logical explanations from being natural. |
13926 | Best explanations, especially natural ones, need grounding, notably by persistent objects [Haslanger] |
Full Idea: I am not resting my ontology on a simple 'argument to the best explanation'. ..What I want to say is that there are general demands on a kind of explanation, in particular, natural explanation, which require that there are persisting things. | |
From: Sally Haslanger (Persistence, Change and Explanation [1989], 5) | |
A reaction: This is a really nice idea - that best explanation is not just about specific cases, but also about best foundations for explanations in general, which brings in our metaphysics. I defend the role of essences in these best explanations. |
1495 | Anaximander introduced the idea that the first principle and element of things was the Boundless [Anaximander, by Simplicius] |
Full Idea: Anaximander said that the first principle and element of existing things was the boundless; it was he who originally introduced this name for the first principle. | |
From: report of Anaximander (fragments/reports [c.570 BCE], A09) by Simplicius - On Aristotle's 'Physics' 9.24.14- | |
A reaction: Simplicius is quoting Theophrastus |
405 | The essential nature, whatever it is, of the non-limited is everlasting and ageless [Anaximander] |
Full Idea: The essential nature, whatever it is, of the non-limited is everlasting and ageless. | |
From: Anaximander (fragments/reports [c.570 BCE], B2), quoted by (who?) - where? |
13222 | The Boundless cannot exist on its own, and must have something contrary to it [Aristotle on Anaximander] |
Full Idea: Those thinkers are in error who postulate ...a single matter, for this cannot exist without some 'perceptible contrariety': this Boundless, which they identify with the 'original real', must be either light or heavy, either hot or cold. | |
From: comment on Anaximander (fragments/reports [c.570 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 329a10 | |
A reaction: A dubious objection, I would say. If there has to be a contrasting cold thing to any hot thing, what happens when the cold thing is removed? |
404 | Things begin and end in the Unlimited, and are balanced over time according to justice [Anaximander] |
Full Idea: The non-limited is the original material of existing things; their source is also that to which they return after destruction, according to necessity; they give justice and make reparation to each other for injustice, according to the arrangement of Time. | |
From: Anaximander (fragments/reports [c.570 BCE], B1), quoted by Simplicius - On Aristotle's 'Physics' 24.13- | |
A reaction: Simplicius is quoting Theophrastus |
1746 | The parts of all things are susceptible to change, but the whole is unchangeable [Anaximander, by Diog. Laertius] |
Full Idea: The parts of all things are susceptible to change, but the whole is unchangeable. | |
From: report of Anaximander (fragments/reports [c.570 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.An.2 |
