To attempt the destruction of our passions is the height of folly. What a noble aim is that of the zealot who tortures himself like a madman in order to desire nothing, love nothing, feel nothing, and who, if he succeeded, would end up a complete monster!
Interpretation
Suppressing one's emotions is foolish and can lead to a loss of humanity.
Denis Diderot argues that attempting to eliminate our passions and emotions is not only misguided but may also lead to a loss of our essential humanity. The zealot who tries to desire, love, and feel nothing becomes a monster, as emotions are integral to our existence and identity. Diderot emphasizes the importance of embracing our passions rather than denying them, suggesting that doing so can lead to a richer and more meaningful life.
