"Man and generally any rational being exists as an end in himself, not merely as a means to be arbitrarily used by this or that will, but in all his actions, whether they concern himself or other rational beings, must always be regarded at the same time as an end" (146).
“Kant's thesis is that human history can be made theoretically intelligible to us only by finding in it a natural end, which is the full (hence temporally endless) development of the natural, predispositions o f the human species (I 8:18).”
If this is Kant's final thesis, what can we say that he has discovered in definite terms? He seems to suggest that history can be defined in how things ended, but how does this help people in current situations? If things are only explained at the end, how do people understand things in the moment with out relying on outdated and possibly irrelevant stations?
Kant states, “…the worth of any object which is to be acquired by our action is always conditional. Beings whose existence depends not on our will but on nature’s, have nevertheless, if they are nonrational beings, only a relative value as means, and are therefore called things; rational beings, on the contrary, are called persons, because their very nature points them out as ends in themselves, that is as something which must not be used merely as means…” (p 146). Kant is placing intrinsic value on humans, while placing instrumental value on all things used by humans to fulfill their objective ends. This principle has some flaws, however. How does such a theory play out in the example of murder? If one human kills another to help fulfill her own objective end, does the victim now lose all intrinsic value and become a thing? How does human control (or lack thereof) play into the objective principle?
Kant calls it man's duty to obtain self perfection. In this endeavor man will be moral, right and good. Kant's philosophy seems to act more as a religion and less as law; for the man that rejects Kant's notion of duty to oneself is not subject to the consequences of his own conscience. That man can only be subject to the consequences of law and order. How could Kantian ethical theory alone be used to create a judicial system? And if it could be created would it be practical?
