A man who is very busy seldom changes his opinions.

Out of passions grow opinions; mental sloth lets these rigidify into convictions

Everything that is ponderous, vicious and pompously clumsy, all long-winded and wearying kinds of style, are developed in great variety among Germans

The snake which cannot cast its skin has to die. As well the minds which are prevented from changing their opinions; they cease to be mind.

Love is more afraid of change than destruction

Such a man as instinctively feeds on pure ambrosia and leaves alone the indigestible in things.
