Time-AtomsPosted: July 28, 2017
This is the third in a series of posts on skepticism (and Goose Island beers.) The earlier posts can be found here.
We are told by Moses Maimonides that the predominant Muslim scholars of his day were atomists. Much like most people today, these mutakallimūn believe that all matter is composed of indivisible particles. More controversially, however, they also believe that time itself is composed of time-atoms. Maimonides claims that this belief is derived from Aristotle’s assertion that time, space, and motion “are of the same nature” because they can be divided in constant proportions to each other. So if all matter is divisible into a finite number of atoms, then time cannot be infinitely divisible. To maintain constant proportions to the nth degree, time must also be divisible only a finite number of times. The result of the final division is an indivisible unit of time.
A consequence of these time-atoms is that each moment must be discrete from that which precedes or follows. And, more importantly, the characteristics of each time atom adhere to that time-atom alone and do not transfer from one moment to the next. So all accidents (“such as colour, smell, motion, or rest”) lack duration. For example, the only reason that a beer is amber in color one moment and continues to be the same color in the next moment is God actively creating each atom in each moment. If we were to add green food coloring to beer (for some reason), it would probably turn green. But the “greenness” of the dye ceases to exist in the very instant that the beer comes in contact with it, and God must create the greenness anew in the beer.
Obviously, the beliefs of the mutakallimūn are not consistent with skepticism. (The fact that they are beliefs at all is a dead giveaway.) But some of their consequences certainly appear skeptical. For one thing, these beliefs implicitly deny cause and effect. The addition of green food coloring to beer may result in green beer 10 times out of 10, but the mutakallimūn attribute the change to the will of God, not to some principle of the dye acting upon the beer. This is quite reminiscent of Hume’s argument against inductive reasoning. We cannot come to a rational conclusion that some specific cause always has some specific effect, because that is merely an assumption based on our limited experiences. It is always possible that we are missing something or that some change might disrupt our supposed “law” of cause and effect.
Likewise, the idea that physical attributes do not have duration squares with a thought of Hume’s. Hume argued that to believe in causation, one would have to first identify some law that the future is always similar to the past. But even if such a law does exist, we have no way of knowing it. As a result, it is unreasonable to form any belief as to what will happen in the future, even with things that we observe to be regular and predicable. Although the mutakallimūn apparently believe that God constantly creates attributes through time to create the appearance of continuity, they, like Hume are unwilling to acknowledge any law that the future must be like the present.
The great caveat in this whole line of thought is that one need not actively deny that the addition of food coloring will change the color of the beer. We are entitled to rely on practical experience to help us through our day. The issue is whether we can, through reason, come to believe that causes will always have effects and that the so-called laws of the universe will be the same tomorrow as they are today. The mutakallimūn doubt both of those, but believe in a certain explanation of the universe and that the will of God creates the illusion of continuity. The skeptics, on the other hand, simply withholds belief outright.
Beer of the week: Honkers Ale – No doubt about this offering from Goose Island. This copper-colored bitter is quite nice. It is just a solid, malty ale with a finish that is just bitter enough to balance it out.
Reading of the week: The Guide for the Perplexed by Moses Maimonides – This selection from Chapter LXXIII of Part I lists the twelve propositions common to all mutakallimūn, as well as some of the consequences of those propositions. Regarding time-atoms, Maimonides writes “The Mutakallemim did not at all understand the nature of time.”
Question of the week: How can one square the skeptic’s rejection of causation and the reasonable confidence that flicking the light switch actually does cause the lights to come on?
