Beauty is the result of having been through an experience all the way through to the end - therefore it has a poignancy. Beauty that is singular always comes from following an experience to the point where you can go no further.

The art of mastering life is the prerequisite for all further forms of expression whether they are paintings sculptures tragedies or musical compositions.
Surely all art is the result of one's having been in danger of having gone through an experience all the way to the end where no one can go any further.
The private interest of the individual would not be sufficiently provided for by reasonable and cool self-love alone therefore the appetites and passions are placed within as a guard and further security without which it would not be taken due care of.
