It is reason that engenders self-love, and reflection that strengthens it; it is reason that makes man shrink into himself; it is reason that makes him keep aloof from everything that can trouble or afflict him: it is philosophy that destroys his connections with other men; it is in consequence of her dictates that he mutters to himself at the sight of another in distress, You may perish for aught I care, nothing can hurt me. Nothing less than those evils, which threaten the whole species, can disturb the calm sleep of the philosopher, and force him from his bed.
