24 ideas
| 5791 | Reduction is either by elimination, or by explanation [Searle] |
| Full Idea: One sense of 'reduction' is eliminative, in getting rid of a phenomenon by showing that it is really something else (as the earth's rotation eliminates 'sunsets'), but another sense does not get rid of it (as in the explanation of solidity by molecules). | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.2) | |
| A reaction: These are bad analogies. You can't 'eliminate' a sunset - you just accept that the event is relative to a viewpoint. If we are discussing ontology, we will not admit the existence of sunsets, but we won't have an ontological category of 'solidity' either. |
| 5799 | Eliminative reduction needs a gap between appearance and reality, as in sunsets [Searle] |
| Full Idea: Eliminative reductions require a distinction between reality and appearance; for example, the sun appears to set but the reality is that the earth rotates. | |
| From: John Searle (The Mystery of Consciousness [1997], Concl 2.10) | |
| A reaction: A bad analogy. You don't 'eliminate' sunsets. It is just 'Galilean' relativity - you thought it was your train moving, then you discover it was the other one. You don't eliminate hallucinations when you show that they don't correspond to reality. |
| 5790 | A property is 'emergent' if it is caused by elements of a system, when the elements lack the property [Searle] |
| Full Idea: An emergent property of a system is causally explained by elements of the system, but it is not a property of the elements, and cannot be explained by a summation of their properties. The behaviour of H2O explains liquidity, but molecules aren't liquid. | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.1) | |
| A reaction: The genie is 'emergent' from the lamp, and so (in Searle's meaning) is the lamp's solidity. I agree that the mind is 'emergent' in Searle's very weak sense, if that only means that one neuron can't be conscious, but lots together can. |
| 5792 | Explanation of how we unify our mental stimuli into a single experience is the 'binding problem' [Searle] |
| Full Idea: The 'binding problem' is how to explain how the brain binds all our different stimuli into a single unified experience of an object. | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.2) | |
| A reaction: This may be the best way of expressing what philosophers call (after Chalmers) the 'Hard Question'. Large objects are held together by gravity, and small objects by electro-magnetism. We don't see a 'binding problem' in the function of a leaf. |
| 5786 | A system is either conscious or it isn't, though the intensity varies a lot [Searle] |
| Full Idea: A system is either conscious or it isn't, but within the field of consciousness there are states of intensity ranging from drowsiness to full awareness. | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.1) | |
| A reaction: I think this all-or-nothing view is the last vestiges of Cartesian dualism, and is quite wrong. Heaps of neuroscience (about blindsight, subliminal awareness, neurosis etc.) says we will never understand the mind if we think it is only the conscious part. |
| 5794 | Consciousness has a first-person ontology, which only exists from a subjective viewpoint [Searle] |
| Full Idea: Consciousness has a first-person or subjective ontology, by which I mean that conscious states only exist when experienced by a subject and they exist only from the first-person point of view of that subject. | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.5 App) | |
| A reaction: I think this is nonsense, and I don't think Searle believes it. He ruthlessly attacks so-called 'eliminativists', but the definition he gives here would make him an eliminativist about other minds. There is no such thing as 'first-person' ontology. |
| 5795 | There isn't one consciousness (information-processing) which can be investigated, and another (phenomenal) which can't [Searle] |
| Full Idea: There are not two kinds of consciousness, an information-processing consciousness that is amenable to scientific investigation and a phenomenal, what-it-subjectively-feels-like form of consciousness that will forever remain mysterious. | |
| From: John Searle (The Mystery of Consciousness [1997], Concl.1) | |
| A reaction: Fodor appears to be the main target of this remark. The view that we can explain intentionality but not qualia is currently very fashionable. I am sympathetic to Searle here. Consciousness isn't an epiphenomenon, it is essential to all thought. |
| 5788 | The use of 'qualia' seems to imply that consciousness and qualia are separate [Searle] |
| Full Idea: I am hesitant to use the word 'quale/qualia', because it gives the impression that there are two separate phenomena, consciousness and qualia. | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.1) | |
| A reaction: He is trying to resist going back to 'sense-data', sitting uneasily between reality and our experience of it. Personally I am quite happy with qualia as an aspect of consciousness - just as I am happy with consciousness as an 'aspect' of brain. |
| 5789 | I now think syntax is not in the physics, but in the eye of the beholder [Searle] |
| Full Idea: It seems to me now that syntax is not intrinsic to the physics of the system, but is in the eye of the beholder. | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.1) | |
| A reaction: This seems right, in that whether strung beads are a toy or an abacus depends on the user. It doesn't follow that the 'beholder' stands outside the physics. A beholder is another physical system, of a particular type of high complexity. |
| 5798 | Consciousness has a first-person ontology, so it cannot be reduced without omitting something [Searle] |
| Full Idea: Consciousness has a first-person or subjective ontology and so cannot be reduced to anything that has third-person or objective ontology. If you try to reduce or eliminate one in favour of the other you leave something out. | |
| From: John Searle (The Mystery of Consciousness [1997], Concl 2.10) | |
| A reaction: Misconceived. There is no such thing as 'first-person' ontology, though there are subjective viewpoints, but then a camera has a viewpoint which is lost if you eliminate it. If consciousness is physical events, that leaves viewpoints untouched. |
| 5787 | There is non-event causation between mind and brain, as between a table and its solidity [Searle] |
| Full Idea: The solidity of a table is explained causally by the behaviour of the molecules of which it is composed, but the solidity is not an extra event, it is just a feature of the table. This non-event causation models the relationship of mind and brain. | |
| From: John Searle (The Mystery of Consciousness [1997], Ch.1) | |
| A reaction: He calls it 'non-event' causation, while referring to the 'behaviour of molecules'. Ask a physicist what a 'feature' is. Better to think of it as one process 'emerging' as another process at the macro-level. |
| 5797 | The pattern of molecules in the sea is much more complex than the complexity of brain neurons [Searle] |
| Full Idea: The pattern of molecules in the ocean is vastly more complex than any pattern of neurons in my brain. | |
| From: John Searle (The Mystery of Consciousness [1997], Concl 2.6) | |
| A reaction: A nice warning for anyone foolish enough to pin their explanatory hopes simply on 'complexity', but we would not be so foolish. A subtler account of complexity (e.g. by Edelman and Tononi) might make brains much more complex than oceans. |
| 5796 | If tree rings contain information about age, then age contains information about rings [Searle] |
| Full Idea: You could say that tree-rings contain information about the age of a tree, but you could as well say that the age of a tree in years contains information about the number of rings in a tree stump. ..'Information' is not a real causal feature of the world. | |
| From: John Searle (The Mystery of Consciousness [1997], Concl 2.5) | |
| A reaction: A nice point for fans of 'information' to ponder. However, you cannot deny the causal connection between the age and the rings. Information has a subjective aspect, but you cannot, for example, eliminate the role of DNA in making organisms. |
| 21740 | I doubt whether ethics is part of philosophy [Russell] |
| Full Idea: I hardly think myself that ethics ought to be included in the domain of philosophy. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch.22) | |
| A reaction: He declines to give his reasons. The implication of the chapter is that ethics is essentially a social and political matter, so that individual ethical guidelines are unimportant. Maybe the woolliness of ethics was also an impediment. |
| 21741 | 'You ought to do p' primarily has emotional content, expressing approval [Russell] |
| Full Idea: A sentence like 'You ought to do so-and-so' primarily has an emotional content. It means ' this is the act towards which I feel the emotion of approval'. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch 22) | |
| A reaction: I don't understand how I can say 'you ought to do p', and very clearly mean that the situation would be altogether better if p, only to be told by some philosopher that what I thought was a sensible judgement is actually an emotional outburst. |
| 21746 | Unlike hate, all desires can be satisfied by love [Russell] |
| Full Idea: If harmonious desires are what we should seek, love is better than hate, since, when two people love each other, both can be satisfied, whereas when they hate each other one at most can achieve the object of his desire. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch 22) | |
| A reaction: A wonderful example of cool philosophical objectivity! Of course it is not true, because the fact that two people love one another doesn't not prevent them from having some incompatible desires, as every couple knows. |
| 21747 | Goodness is a combination of love and knowledge [Russell] |
| Full Idea: The good life is one inspired by love and guided by knowledge. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch 22) | |
| A reaction: Forty years later, Russell's famous filmed message to posteriority said exactly this. In decision making, get the facts; in relationships, show love and tolerance. I find both parts inspiring. |
| 21743 | In wartime, happiness is hating the enemy, because it gives the war a purpose [Russell] |
| Full Idea: During and immediately after the war [14-18], those who hated the Germans were happier than those who still regarded them as human beings, because they could feel that what was being done served a good purpose. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch 22) | |
| A reaction: A striking remark. There are lots of situations where hatred seems to increase happiness. Russell is roughly defending consequentialism. |
| 21742 | Originally virtue was obedience, to gods, government, or custom [Russell] |
| Full Idea: Historically, virtue consisted at first of obedience to authority, whether that of the gods, the government, or custom. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch 22) | |
| A reaction: Russell proceeds to demolish such a theory, which he finds it fairly easy to do. In Nietzsche's terms, he is only describing slave virtue. Each role in the world has its own virtues (and functions). Which gods are the most virtuous? |
| 21745 | Act so as to produce harmonious rather than discordant desires [Russell] |
| Full Idea: The supreme moral rule should be: Act so as to produce harmonious rather than discordant desires. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch 22) | |
| A reaction: Russell makes no reference to Kant, but this is obviously intended to rebut the more rationalist Kantian view of what is imperative. The use of 'harmonious' chimes in best with Plato's account of the soul in 'Republic'. |
| 21744 | Legally curbing people's desires is inferior to improving their desires [Russell] |
| Full Idea: To force a man to curb his desires, as we do by the criminal law, is not nearly so satisfactory as to cause him genuinely to feel the desires which promote socially harmonious conduct. | |
| From: Bertrand Russell (An Outline of Philosophy [1927], Ch 22) | |
| A reaction: It is hard to disagree, but improving the desires of selfish and even vicious people is a rather challenging task. |
| 1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
| Full Idea: Archelaus was the first person to say that the universe is boundless. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
| 22891 | We could be aware of time if senses briefly vibrated, extending their experience of movement [Russell, by Bardon] |
| Full Idea: Russell suggested, in defence of an empiricist theory of time-awareness, that a sense organ goes on vibrating, like a piano string, for while after the stimulation. Thus we can see the movement of a second hand, seen in several places at once. | |
| From: report of Bertrand Russell (An Outline of Philosophy [1927]) by Adrian Bardon - Brief History of the Philosophy of Time 2 'Realism' | |
| A reaction: Hm. If they were vibrating the last experience, they couldn't pick up the new one. When something fast happens the brain resonates fortissimo! If your eyes are moving it will be different neurons that get fired at each instant. |
| 5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
| Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
| A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
