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).
Gist of Idea
Reduction is either by elimination, or by explanation

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.
5790 | A property is 'emergent' if it is caused by elements of a system, when the elements lack the property [Searle] |
5786 | A system is either conscious or it isn't, though the intensity varies a lot [Searle] |
5788 | The use of 'qualia' seems to imply that consciousness and qualia are separate [Searle] |
5789 | I now think syntax is not in the physics, but in the eye of the beholder [Searle] |
5787 | There is non-event causation between mind and brain, as between a table and its solidity [Searle] |
5792 | Explanation of how we unify our mental stimuli into a single experience is the 'binding problem' [Searle] |
5791 | Reduction is either by elimination, or by explanation [Searle] |
5794 | Consciousness has a first-person ontology, which only exists from a subjective viewpoint [Searle] |
5798 | Consciousness has a first-person ontology, so it cannot be reduced without omitting something [Searle] |
5799 | Eliminative reduction needs a gap between appearance and reality, as in sunsets [Searle] |
5796 | If tree rings contain information about age, then age contains information about rings [Searle] |
5797 | The pattern of molecules in the sea is much more complex than the complexity of brain neurons [Searle] |
5795 | There isn't one consciousness (information-processing) which can be investigated, and another (phenomenal) which can't [Searle] |
