No man learns to know his inmost nature by introspection, for he rates himself sometimes too low, and often too high, by his own measurement. Man knows himself only by comparing himself with other men; it is life that touches his genuine worth.
There is no remedy but love for the great superiority of others
Willing is not enough, we must do.
What matters in art is not thinking but making.
A state of affairs which leads to daily vexation is not the right state.
If I work incessantly to the last, nature owes me another form of existence when the present one collapses.
