No sacrifice is worth the name unless it is a joy. Sacrifice and a long face go ill together. Sacrifice is 'making sacred'. He must be a poor specimen of humanity who is in need of sympathy for his sacrifice.
Men who have sacrifice their well-being, and even their lives, for the cause of truth or the public good, are, from an empirical point of view - which scorn ("fait fi", Fr.) virtue and altruism - regarded as insane or fools; but, from a moral standpoint, they are heros who do honour ("qui honorent", Fr.) humanity.
