Leave me to my own absurdity. - Sophocles

"There is no more deadly peril than disobedience;
States are devoured by it, homes laid in ruins,
Armies defeated, victory turned to rout.
White simple obedience saves the lives of hundreds
Of honest folk." - Creon

Though he has watched a decent age pass by,
A man will sometimes still desire the world.
I swear I see no wisdom in that man.
The endless hours pile up a drift of pain
More unrelieved each day: and as for pleasure,
When he is sunken in excessive age,
You will not see his pleasure anywhere.
The last attendant is the same for all,
Old men and young alike, as in its season
Man's heritage of underworld appears:
There being no epithalamion,
No music and no dance. Death is the finish.

Not to be born beats all philosophy.
The second best is to have seen the light
And then to go back quickly whence we came.
The feathery follies of his youth once over,
What trouble is beyond the range of man?
What heavy burden will he not endure?
Jealousy, faction, quarreling, and battle — The bloodiness of war, the grief of war.
And in the end he comes to strengthless age,
Abhorred by all men, without company,
Unfriended in that uttermost twilight
Where he must live with every bitter thing.

Knowledge must come through action; you can have no test which is not fanciful, save by trial.
