The more our moral thoughts are abundant and solid the more engrossing they are and oppressive… We need our soul to be instructed in the means of sustaining evils and of fighting them off, instructed too in the rules of right-living and right-believing; and we need to awaken her to practise so fine an endeavour. But in the case of a soul of the common sort this must be done with moderation and some laxity: keep her continually tensed and you drive her mad.
Once upon a time I used to mark as exceptional the dark, depressing days: those days are now my routine ones; it is the ones which are beautiful and serene which are extraordinary now. I am close to the point when I shall jump for joy and accept anything which does not actually hurt as some new favour.
~ Montaigne, The Complete Essays (1587-88)
