Certain Quotes - page 80
(...) no spectator is needed, because your consciousness basically is your reality model. I think that consciousness is the way information feels when being processed in certain complex ways. Since the different parts of your brain interact with each other, different parts of your reality model can interact with each other, so the model of you can interact with your model of the outside world, giving rise to the subjective sensation of the former perceiving the latter.
Max Tegmark
We humans replace the bulk of both our "hardware” (e. g., our cells) and our "software” (e. g., our memories) many times in our life span. Nonetheless, we perceive ourselves as stable and permanent. Likewise, we perceive objects other than ourselves as permanent. Or rather, what we perceive as objects are those aspects of the world that display a certain permanence. For instance, when observing the ocean, we perceive the moving waves as objects because they display a certain permanence, even though the water itself is only bobbing up and down. Similarly (...) we perceive only those aspects of the world that are fairly stable against quantum decoherence.
Max Tegmark
This implication of the Mathematical Universe Hypothesis is pretty radical, so please pause your reading for a moment to take it in and think about it. What you're aware of right at this moment feels not like a photo but like a movie clip. This movie isn't reality-it exists only in your head, as part of your brain's reality model. It contains lots of information about the actual external physical reality-as long as you aren't dreaming or hallucinating-but still constitutes only a very heavily edited version of reality, akin to the evening news on TV, mainly featuring certain highlights of patterns nearby in space and time that your brain thinks are useful for you to be aware of.
Max Tegmark
They [mathematicians] only take those things into consideration, of which they have clear and distinct ideas, designating them by proper, adequate, and invariable names, and premising only a few axioms which are most noted and certain to investigate their affections and draw conclusions from them, and agreeably laying down a very few hypotheses, such as are in the highest degree consonant with reason and not to be denied by anyone in his right mind. In like manner they assign generations or causes easy to be understood and readily admitted by all, they preserve a most accurate order, every proposition immediately following from what is supposed and proved before, and reject all things howsoever specious and probable which can not be inferred and deduced after the same manner.-Barrow, Isaac.
Isaac Barrow
I cannot see why it is necessary that every deduction from algebra should be bound to certain conventions incident to an earlier stage of mathematical learning, even supposing them to have been consistently used up to the point in question. I should not care if any one thought this treatise unalgebraical, but should only ask whether the premises were admissible and the conclusions logical.
Augustus De Morgan
When... we have a series of values of a quantity which continually diminish, and in such a way, that name any quantity we may, however small, all the values, after a certain value, are severally less than that quantity, then the symbol by which the values are denoted is said to diminish without limit. And if the series of values increase in succession, so that name any quantity we may, however great, all after a certain point will be greater, then the series is said to increase without limit. It is also frequently said, when a quantity diminishes without limit, that it has nothing, zero or 0, for its limit: and that when it increases without limit it has infinity or ∞ or 1⁄0 for its limit.
Augustus De Morgan
The important Keynesian insight is that a high propensity to save will not generate high national saving unless it goes into investment, into accumulation of real capital. The "paradox of thrift" makes this point in an extreme way. In certain circumstances, when there is no demand for investment around, the economy can be no better off, or even worse off, if a thrifty public cuts consumption.
James Tobin
Let me rule out at once any God who has personally spoken to anyone or issued instructions to men. That some men believe they have been spoken to by God, I am certain. That's for them to believe. I don't believe Moses came down from the mountain with any tablets he did not go up with. I believe mankind in general has a need to believe in higher powers and an existence not limited to the physical duration of the body. But these needs are hopes, and believing them doesn't make them true. I believe mankind feels a need to gather in churches, whether physical or social. I've spent hours and hours in churches all over the world. I sit in them not to pray, but to gently nudge my thoughts toward wonder and awe. I am aware of the generations there before me and the reassurance of tradition.
Roger Ebert
The result is a horrible mess of a movie, without shape, trajectory or purpose - a one joke movie, if it had one joke. The two characters wander witlessly past the bizarre backdrops of Las Vegas (some real, some hallucinated, all interchangeable) while zonked out of their minds. Humor depends on attitude. Beyond a certain point, you don't have an attitude, you simply inhabit a state. I've heard a lot of funny jokes about drunks and druggies, but these guys are stoned beyond comprehension, to the point where most of their dialog could be paraphrased as "eh?"... As for Depp, what was he thinking he made this movie? He was once in trouble for trashing a New York hotel room, just like the heroes of Fear and Loathing in Las Vegas. What was that? Research? After River Phoenix died of an overdose outside Depp's club, you wouldn't think Depp would see much humor in this story - but then, of course, there *isn't* much humor in this story.
Roger Ebert
The function [of objective thinking] is to reduce all phenomena which bear witness to the union of subject and world, putting in their place the clear idea of the object as in itself and of the subject as pure consciousness. It therefore severs the links which unite the thing and the embodied subject, leaving only sensible qualities to make up our world (to the exclusion of the modes of appearance which we have described), and preferably visual qualities, because these give the impression of being autonomous, and because they are less directly linked to our body and present us with an object rather than introducing us into an atmosphere. But in reality all things are concretions of a setting, and any explicit perception of a thing survives in virtue of a previous communication with a certain atmosphere.
Maurice Merleau-Ponty
Human beings do not live in the objective world alone, nor alone in the world of social activity as ordinarily understood, but are very much at the mercy of the particular language which has become the medium of expression for their society. It is quite an illusion to imagine that one adjusts to reality essentially without the use of language and that language is merely an incidental means of solving specific problems of communication or reflection. The fact of the matter is that the ‘real world' is to a large extent unconsciously built up on the language habits of the group... We see and hear and otherwise experience very largely as we do because the language habits of our community predispose certain choices of interpretation.
Steven Pinker
Suppose the reasoning centers of the brain can get their hands on the mechanisms that plop shapes into the array and that read their locations out of it. Those reasoning demons can exploit the geometry of the array as a surrogate for keeping certain logical constraints in mind. Wealth, like location on a line, is transitive: if A is richer than B, and B is richer than C, then A is richer than C. By using location in an image to symbolize wealth, the thinker takes advantage of the transitivity of location built into the array, and does not have to enter it into a chain of deductive steps. The problem becomes a matter of plop down and look up. It is a fine example of how the form of a mental representation determines what is easy or hard to think.
Steven Pinker
