By Alfred Adler
The greater the feeling of inferiority that has been experienced, the more powerful is the urge to conquest and the more violent the emotional agitation.
Exaggerated sensitiveness is an expression of the feeling of inferiority.
The beauty of the soul shines out when a man bears with composure one heavy mischance after another, not because he does not feel them, but because he is a man of high and heroic temper.
Temperance is a mean with regard to pleasures.
