Quote by Fyodor Dostoyevsky
Sarcasm: the last refuge of modest and chaste-souled people when the privacy of their soul is coarsely and intrusively invaded.

Summary
This quote suggests that sarcasm is employed by humble and virtuous individuals as a form of defense when their inner thoughts and emotions are invaded and exposed in a crude and intrusive manner. It implies that instead of openly expressing their true feelings, these individuals rely on sarcasm to maintain a sense of privacy and protect their modesty and integrity. Sarcasm becomes a coping mechanism, allowing them to indirectly express themselves while maintaining a guarded exterior.
