The ideal for humanity cannot be achieved, because humanity is infinite (it is, of course, most likely to end sometime, but not a fact; when this end is not known, so we will consider it infinite) and, accordingly, it is infinite in its development. And the ideal is a function of the finite. A particular person is finite and can achieve his own ideal.
