I feel that, as a person who loves philosophy, I have to be my own worst critic. So I was doing some thinking about this and decided to get some second hand opinions.
ok, so our natural rights to life, liberty, and estate are derived from our ability to reason. The reason animals do not have rights is because they lack the ability to reason. The reason children do not have full access to the natural rights of man is because their ability to reason is still developing. It is also the reason that guardians have the rights to people in a coma, or mentally handicapped.
So my hypothetical situation is this: is it possibe for a man to be completely devoid of reason? The only instance I can think of would be a person in a coma, or perhaps cases of extreme mental retardation.
Assuming that the man does not have reason but is still living, does that mean he has the same rights, more or less, than an animal?
What is the value of such a person (utterly devoid of humanity, a mere piece of
meat)? Such a person is the creation of a parent, or stand-in creator such as a
guardian. As such, the person is the “property” (creation) of this other person. The
creator has the right to the “disposition” of their property as they see fit.
This is only meaningful if the “piece of meat” is in reality a “piece of meat”.
If there is ANY consciousness, which implies some conceptualization and therefore
some reason, then they must be afforded full sovereignty as individuals, and be
protected by the police agency (government) from any violation of the "trader
principle" of others.
This brings me to my next point, one most difficult to grasp: nominally, under a purely capitalist system, one would able to beat their animals. It isn’t an objectivist thing to do, but neither is doing hard drugs (yet those would also be free in a Capitalistic society.) The reason that man may subject his animals to pain is because the animal does not possess rights, due to their lack of reason. So the next point is, since that mentally handicapped man who lacks reason would have the intellect more or less like an animal, does that mean he is someone else’s property, and thus subject to the owner’s whims, even if they involved beatings?
My opinion. Animals do reason (as anyone who owns a dog or cat knows) but they
are not human.
Human reason is the granting faculty for “rights”. Not simple reason.
If someone were to “for verifiably no reason”, beat their dog to death on the
street, I would judge that person as being pathologically irrational and have no
further dealings (trade) with that person, and I would promulgate what I witnessed
to any who would listen. This is not slander/libel, but the truth.
Beating one’s animals would ellicit MUCH negative attention, even in a purely
capitalist society, and would be the equivalent of violating the “trader principle” on
oneself.
Basing ANYTHING on whim, is irrational.
You are stinging together a series of irrationalities that those who would
characterize an “objectivist society” as a bunch of euthenizing, poor oppressing,
animal abusing hedonists.
But thanks for not believing that yourself,.. as it’s irrational.
