They make one journey after another and change spectacle for spectacle. As Lucretius says, ‘Thus each man ever flees himself.’ But to what end, if he does not escape himself? He pursues and dogs himself as his own most tedious companion. And so we must realize that our difficulty is not the fault of the places but of ourselves. We are weak in enduring anything, and cannot put up with toil or pleasure or ourselves or anything for long. This weakness has driven some men to their deaths; because by frequently changing their aims they kept falling back on the same things and had left themselves no room for novelty. They began to be sick of life and the world itself, and out of their enervating self-indulgence arose the feeling ‘How long must I face the same things?’
