The greater part of all the mischief in the world arises from the fact that men do not sufficiently understand their own aims. - Johann Wolfgang von Goethe

So gewiß ist der allein glücklich und groß, der weder zu herrschen noch zu gehorchen braucht, um etwas zu sein!

Theories usually result from the precipitate reasoning of an impatient mind which would like to be rid of phenomena and replaces them with images, concepts, indeed often with mere words.

Dear me! how long is art!
And short is our life!
I often know amid the scholar's strife
A sinking feeling in my mind and heart.
How difficult the means are to be found
By which the primal sources may be breached;
And long before the halfway point is reached,
They bury a poor devil in the ground.
