Sorry about arriving late to this discussion.
A few posts back, Martin Radwin asked which of the following accounts of the origin of species Aristotle adhered to:
Quote
(1) All species of life have always existed
2) All species of life were created at once by a creator
3) All species of life just appeared sponteneously
4) All species of life evolved through a series of steps from simpler life forms
Definitely not (4). Aristotle believed in the fixity of species. You can't get from some antiquated land-dwelling mammal to a whale through a series of successive changes, not even over many generations.
Definitely not (2). Aristotle's god is too uninvolved in the affairs of the universe to go about creating anything. He wouldn't have taken the trouble to create the heavenly bodies, let alone life forms that come into being and pass away.
As for (3), Aristotle couldn't rule out "spontaneous generation" of living things from some inanimate matrix (the hackneyed example is maggots arising from rotting meat, though I don't know his biological works very well, and that example may not be his). But it wouldn't have been part of an evolutionary scheme.
The standard interpretation of Aristotle is (1).
Ellen asked what kind of biology Rand got exposed to in her Russian education. That
is a question for Chris Sciabarra. We can set some limits on the inquiry, though. Rand left Russia well before Josef Stalin made Trofim D. Lysenko his pet biologist. On the other hand, one wonders how up-to-date education in biology was during the early Soviet years. I know from some work I've done on Jean Piaget (whose education in biology basically took place between 1906 and 1917) that Lamarckian doctrines were still generally accepted in the French-speaking world during that period; Piaget would never shake them off completely. The neo-Darwinian synthesis was just under way in 1920, and early reactions to modern genetics included grossly confused notions (from today's point of view); for instance, that "mutationism" is incompatible with "Darwinism," so you must pick one or the other.
I also wonder what Rand's early exposure to "social Darwinism" was like (and whether it took place before she arrived in the US). She hated Herbert Spencer's ideas (on the basis of what acquaintance I don't know). How did she think Spencer's theories related to more modern evolutionary conceptions?
Dragonfly's suggestion, that Rand's rejection of theism was partly religious in its motivation (man ought to be the object of worship, not god), strikes me as plausible. If correct, it would shed further light on Rand's insistence that human beings ought to strive for moral perfection.
Whatever the reasons for Rand's wanting to keep evolution at arm's length, its legacy is a weird disconnect about evolution out in some neighborhoods of Rand-land. When presented with "intelligent design," an ARI acolyte will insist that biological evolution is incontrovertible scientific fact and that "intelligent design" advocates are the sheerest of theological obscurantists. Yet, when asked whether evolution has any relevance to metaphysics, epistemology, or ethics, the ARI acolyte, quoting Dr. Peikoff, will insist that evolution is forever outside the scope of philosophy. And when questions are raised as to why Rand was uncomfortable with evolution, well... we know what happened to Neil Parille when he ventured into that territory a while back.
