Why should I believe this? I believe the
brain initiates motion. It is the structure, function, and development of
biological structures and their physiologic function that do this -- and these are all
physical things.
Quote:Since even from the moment of conception there is motion in the body, it follows that there is a soul (in the Aristotelian sense) united with the body even then.
While you are right that a fertilized egg has "motion" (function is a more accurate term), you're completely wrong that it begins at the moment of conception. Individual sperm and individual ova have metabolism, locomotion, gene transcription, protein synthesis, etc. This is true
before fertilization and it remains true
after.
I have a difficult time taking seriously scientific arguments that look to Aristotle but ignore everything between him and now. He died 2300 years ago, more or less, and it was only the intellectual vapidity of European philosophy (really up until Descartes) that elevated him to the degree of grandeur that his legacy has enjoyed.
Aristotle believed in metaphysical chains of causality because he lacked any way to offer a direct physical explanation. But what was logical to science in ancient Greece is simply not applicable to a current understanding of things.
Quote:Well, it seems to me that if you take away the form, you have a corpse which generally will disintegrate into ash.
No, if the physiologic function of the body dies, then it will cease to function as a coherent biological entity. Since consciousness and self-awareness require a working brain, these disappear as well. (This doesn't require death -- it can happen from a head injury or various neurodegenerative illnesses or various medications -- thus proving that your metaphysical "soul" is very much sensitive to
physical injuries.) The corpse lacks defenses against microbes, scavengers, etc, so it decays and its constituent parts are used by other organisms and it eventually disappears.
Quote:Since, therefore, the body does not have an image of humanity except when united with the form, it follows that the humanity of man lies not in the body but in the form.
If you died, you would look an awful lot like a human at first. In fact someone might think you're alive until they check your pulse. So I guess a corpse can STILL be confused for humanity. In fact, so can a wax model.
Quote:Were man solely a body, a man could not have conflicting desires...for example, both a desire to eat the pizza and a revulsion from it.
I guess that means that moths have souls as well, right? I mean they fly around light bulbs until they get burned by them.
There is nothing wrong with having "conflicting desires". Furthermore, something CAN be both true and untrue simultaneously if there are multiple ways of interpreting a) that thing or b) the words used to describe that thing.
