22361 | Contextual values are acceptable in research, but not in its final evaluation [Reichenbach, by Reiss/Sprenger] |
Full Idea: Reichenbach's claim is interpreted as saying that contextual values, which may have contributed to the discovery of a theory, are irrelevant for justifying the acceptance of a theory, and for assessing how evidence bears on theory. | |
From: report of Hans Reichenbach (On Probability and Induction [1938], pp.36-7) by Reiss,J/Spreger,J - Scientific Objectivity 3.2 | |
A reaction: This influential idea is very helpful. It allows Galileo and co to pursus all sorts of highly personal and quirky lines of enquiry, because we only demand full objectivity when it is all over. Very good! |
16062 | A necessary relation between fact-levels seems to be a further irreducible fact [Lynch/Glasgow] |
Full Idea: It seems unavoidable that the facts about logically necessary relations between levels of facts are themselves logically distinct further facts, irreducible to the microphysical facts. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], C) | |
A reaction: I'm beginning to think that rejecting every theory of reality that is proposed by carefully exposing some infinite regress hidden in it is a rather lazy way to do philosophy. Almost as bad as rejecting anything if it can't be defined. |
16061 | If some facts 'logically supervene' on some others, they just redescribe them, adding nothing [Lynch/Glasgow] |
Full Idea: Logical supervenience, restricted to individuals, seems to imply strong reduction. It is said that where the B-facts logically supervene on the A-facts, the B-facts simply re-describe what the A-facts describe, and the B-facts come along 'for free'. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], C) | |
A reaction: This seems to be taking 'logically' to mean 'analytically'. Presumably an entailment is logically supervenient on its premisses, and may therefore be very revealing, even if some people think such things are analytic. |
16060 | Nonreductive materialism says upper 'levels' depend on lower, but don't 'reduce' [Lynch/Glasgow] |
Full Idea: The root intuition behind nonreductive materialism is that reality is composed of ontologically distinct layers or levels. …The upper levels depend on the physical without reducing to it. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], B) | |
A reaction: A nice clear statement of a view which I take to be false. This relationship is the sort of thing that drives people fishing for an account of it to use the word 'supervenience', which just says two things seem to hang out together. Fluffy materialism. |
16064 | The hallmark of physicalism is that each causal power has a base causal power under it [Lynch/Glasgow] |
Full Idea: Jessica Wilson (1999) says what makes physicalist accounts different from emergentism etc. is that each individual causal power associated with a supervenient property is numerically identical with a causal power associated with its base property. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], n 11) | |
A reaction: Hence the key thought in so-called (serious, rather than self-evident) 'emergentism' is so-called 'downward causation', which I take to be an idle daydream. |
18278 | Kant showed that our perceptions are partly constructed from our concepts [Reichenbach] |
Full Idea: It was Kant's great discovery that the object of knowledge is not simply given but constructed, and that it contains conceptual elements not contained in pure perception. | |
From: Hans Reichenbach (The Theory of Relativity and A Priori Knowledge [1965], p.49), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap |
3031 | The greatest good is not the achievement of desire, but to desire what is proper [Menedemus, by Diog. Laertius] |
Full Idea: Hearing someone assert that the greatest good was to succeed in everything that one desires, he said,"It is a much greater good to desire what is proper". | |
From: report of Menedemus (fragments/reports [c.310 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.16.12 |
8410 | A theory of causal relations yields an asymmetry which defines the direction of time [Reichenbach, by Salmon] |
Full Idea: Reichenbach wanted to implement a causal theory of time. He did not stipulate that causes are temporally prior to their effects. Instead, he constructs a theory of causal relations to yield a causal asymmetry which is used to define temporal priority. | |
From: report of Hans Reichenbach (The Direction of Time [1956]) by Wesley Salmon - Probabilistic Causality | |
A reaction: I find his approach implausible. I suspect strong empiricism is behind it - that he wants to build from observable causes to unobservable time, not vice versa. But normal intuition sees time as one of the bedrocks of reality, making events possible. |
14935 | The direction of time is grounded in the direction of causation [Reichenbach, by Ladyman/Ross] |
Full Idea: Reichenbach argued that temporal asymmetry is grounded in causal asymmetry. | |
From: report of Hans Reichenbach (The Direction of Time [1956]) by J Ladyman / D Ross - Every Thing Must Go | |
A reaction: I'm not sure that I can make sense of giving priority either to time or to causation when it comes to this asymmetry. How do you decide which one is boss? |
