Schopenhauer: the individual human being sits quietly, supported by and trusting in the principium individuationis

Just as in a stormy sea that, unbounded in all directions, raises and drops mountainous waves, howling, a sailor sits in a boat and trusts in his frail bark: so in the midst of a world of torments the individual human being sits quietly, supported by and trusting in the principium individuationis (principle of individuation).

• Arthur Schopenhauer, The World as Will and Representation (1819)
