n. repudiation; self-sacrifice; renouncing your own interests in favor of interests of others
No act of abnegation was more pronounced than his refusal of any rewards for his discovery.
Sentence in Classic:
A saint who dwells in a paroxysm of abnegation is a dangerous neighbor; he might communicate to you, by contagion, an incurable poverty, an anchylosis of the joints, which are useful in advancement, and in short, more renunciation than you desire; and this infectious virtue is avoided.
