It
can be said that Aristotle’s Physics ought not to be a part of his
philosophical examination, because what we know as physics is a natural
science, and not a division of philosophy. Such an argument surely misses a
couple of key points, one being that, in our pre-Socratic experience, science
has always come inseparably from philosophy, and Aristotle clearly belongs to
the same tradition; and the other being that what we call physics is not
what Aristotle had in mind using this word. The Greek word physis, meaning
nature, refers to the potential for growth (phyein=make grow)
inherent in all living things striving towards actualization (curiously, the
once highly fashionable new-age term ‘self-actualization’ has
been rather unceremoniously taken from Aristotle’s vocabulary!), which
immediately immerses us in teleology, which in turn belongs to bona fide
philosophy, without any doubt about it whatsoever.
In
fact, Aristotle treats science just like he treats philosophy, which is why
physical, or any other, science is by virtue of this connection an
integral part of his philosophy.
The
physis of a thing, to Aristotle, is its purpose in the order of things,
turning it into a cause, which works for the sake of something, which leads to a discussion of the view that nature works of
necessity without a purpose, as Aristotle discusses the survival of the fittest
in the form taught by Empedocles. This cannot be right, he argues, because
things happen in fixed ways, and when a series has a completion, all preceding
steps are for its sake. Those things are “natural”
which “by a continuous movement
originated from some internal principle arrive at some completion.” (Physics
199b)
It
is very hard today to take such physics seriously, but there is a big
difference between taking something on the authority of ipse dixit and
contemplating upon a weird theory for the sake of a possible inspiration, that
is, a brainstorm. I say that brainstorms happen most frequently when we get off
the track of common sense into the strange fields of eccentricity. It is
extremely strange to call Aristotle an eccentric or to suspect him of
irrationality, when he seems to be the epitome of the opposite, but what makes
all the difference is the fact that we are living in a post-Aristotelian world
and are no longer subdued by his rationalist thinking into an intellectual
submission, which, as we remember, had been the case for two thousand years.
The
second part of Aristotle’s physics discussed here, which is the one that has
contributed the title of this entry, is expounded in his treatise On the
Heavens. There are two physical realities in the universe: one is sublunary,
that is, literally, below the moon (relative to our earth, which is, as
we remember, spherical and rests right in the center of the universe). All
things below the moon are, so-to-speak, mortal, that is, subject to
generation, growth, and decay. They all predictably consist of the Heraclitean
four elements: earth, water, air and fire. All of them (surprise, surprise!)
move rectilinearly. But above all these from the moon upwards are the heavens, where everything is
ungenerated and indestructible. Not only that, but none of the heavenly bodies
partake of the terrestrial four elements. All of them are composed of the
mysterious fifth element and they move in circles, being attached to
heavenly spheres.
With
this natural fairytale we have come to the end of the Aristotelian
subsection, and whatever derogative stuff can be said about the great
Aristotle, the fact that our next magnificent shadow is separated from
him by a distance of two millennia speaks volumes in his behalf and makes his
critics look mean and ugly.
(This
is my last entry of the Aristotle subsection
of the Magnificent Shadows section.
Beginning tomorrow, my wife’s postings of Galina
Sedova’s Bulgakov resume with the chapter Who-R-U, Margarita?)
