I have been thinking on the differentiations between animal and man and it has yielded all but one viable point of divergence.
That point is free will. Not free will in it's typical chemically and mathematically deterministic sense but rather the free will that lets man become free of his biological circumstances. A man can make a "irrational" decision and animals can only make "rational" decisions. (that relies on the contingency that the animal is aware of the most rational decision it can make according to it's genetic nature.)
I also feel it proper to use the term bio-logic in a alternative manner to which it is conventionally used. Instead of biologic meaning in relation to the study of life, I am saying bio (meaning life) - logic (meaning the logic of life.) This term is intended to encapsulate the explicit mental calculations that animals make in order to survive. This includes where to go to feed, how to act in order not to get eaten, but also how to act in order to find a mate. (something that is in the interest of the greater species, an interesting point of conjecture that a primal animal would be presumed to act selfish and yet somehow it has been endowed with a chemical incentive (two really) for it to procreate and reproduce. This makes one laugh at the perfect irony of a perfectly Nietzchean paradox in the animal kingdom.)
Animals make all of their decisions in attempt to survive and keep their family alive. Humans make irrational decisions all of the time, not just the humans with chemical imbalance who take a knife to their children or perhaps themselves, but the everyday man that chooses to do some minute and banal irrationality.
To illustrate, if you were to train a dog to hit itself the dog would most likely fight you or run away. The reaction would be uniform among most animals (or at least my puerile worldview tells me it would be.) But you, the person reading this right now, have the ability to slap yourself across the face, risking scratching out an eye and dying to blood loss, or causing a blood clot in your brain leading you to seize. You can do that right now despite the egregious irrationality the act purports.
This lead me to a couple of questions that I cannot answer myself and would like help with:
First, when and how did the biological free will evolve? What external stimuli caused this evolution? (some sources suggest that unpredictable movement allow for early humans to evade predators) Am I making a fallacious contention claiming that animals cannot act irrationally? Also does anyone know of the first recorded study or research on suicide? Much thanks to any who take the time to answer, and please forgive me for any naivete or logical errors I am only a freshman in high school and my knowledge thus far is all but minimal.
