Zweck sein selbst ist jegliches Tier. Each animal is an end in itself.
We do not exist for the sake of something else. We exist for the sake of ourselves.
The rose is without 'why'; it blooms simply because it blooms. It pays no attention to itself, nor does it ask whether anyone sees it.
It is not with respect to our convenience or discomfort, but with respect to their own nature that the creatures are glorifying to their Artificer.
When you believe that you are not worthwhile in and of yourself, in the back of your mind you also begin to believe that life is not worthwhile in and of itself. It is only worthwhile insofar as it relates to your crusade. It is a kamikaze mission.
If the eyes are open and there is light, seeing occurs; the stimulus is but a condition of the fulfillment of the proper function of the organ, not an outside interruption. To some extent, then, all direction or control is a guiding of activity to its own end; it is an assistance in doing fully what some organ is already tending to do.
Life is teleology par excellence; it is the intrinsic striving towards a goal, and the living organism is a system of directed aims which seek to fulfill themselves.
Talent finds its models, methods, and ends in society, exists for exhibition, and goes to the soul only for power to work. Genius is its own end, and draws its means and the style of its architecture from within.
For just as for a flute-player, a sculptor, or an artist, and, in general, for all things that have a function or activity, the good and the well is thought to reside in the function, so would it seem to be for man, if he has a function.
To be alive is power; existence in itself; without a further function; omnipotence.
A story ... has a sturdy sense of itself of being built out of its own necessity, not just to shelter or beguile you.
