So far as we live and strive at all, our lives are various, are needed for the whole, and are unique.
God is One, all our lives have various and unique places in the harmony of the divine life.
By an individual being, whatever one's metaphysical doctrine, one means an unique being, that is, a being which is alone of its own type, or is such that no other of its class exists.
If I look to see what I ever did that, for all I now know, some other man might not have done, I am utterly unable to discover the certainly unique deed.
The unique eludes us; yet we remain faithful to the ideal of it; and in spite of sense and of our merely abstract thinking, it becomes for us the most real thing in the actual world, although for us it is the elusive goal of an infinite quest.
