6 ideas
| 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! |
| 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 |
| 14367 | An explanation is a causal graph [Woodward,J, by Strevens] |
| Full Idea: On Woodward's manipulationist view, an explanation would take the form of a causal graph. | |
| From: report of James Woodward (Making Things Happen [2003]) by Michael Strevens - No Understanding without Explanation 1 | |
| A reaction: The idea is that causation is all to do with how nature responds when you try to manipulate it. I'm certainly in favour of tying explanation closely to causation. |
| 19941 | Thou shalt love thy neighbour as thyself [Anon (Leviticus)] |
| Full Idea: Thou shalt love thy neighbour as thyself. | |
| From: Anon (Lev) (03: Book of Leviticus [c.700 BCE], 19.18) | |
| A reaction: Most Christians think Jesus originated this thought. Interestingly, this precedes Socrates, who taught a similar idea. |
| 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? |
