There is safety in the midst of danger. What would life be if we didn’t dare to take things in hand?[There is safety in the midst of danger. Wat zou het leven zijn als we niet wat durfden aanpakken.]
There is plenty of courage among us for the abstract but not enough for the concrete, because we allow our daily bits of bravery to evaporate.
The World is full of fools and faint hearts; and yet every one has courage enough to bear the misfortunes, and wisdom enough to manage the Affairs of his neighbour.
Sometimes my courage fails me and I think I ought to stop working, live in the country and devote myself to gardening. But I am held by a thousand bonds, and I don’t know when I shall be able to arrange things otherwise. Nor do I know whether, even by writing scientific books, I could live without the laboratory.
Neither a wise man nor a brave man lies down on the tracks of history to wait for the train of the future to run over him.
Just as courage imperils life, fear protects it.[Siccome l’animosità è pericolo di uita così la paura è sicurità di quella.]
