People praise virtue, but they hate it, they run away from it. It freezes you to death, and in this world you've got to keep your feet warm.

In this quote, Denis Diderot, an influential French philosopher and key figure of the Enlightenment, offers a critique of virtue and its place in society. He suggests that while people may publicly praise virtue, they actually despise it or avoid it when it demands too much. The phrase "it freezes you to death" is a metaphor for how adhering strictly to virtue can isolate you from the rest of society, making you cold and detached from the human connections and pleasures that others seek. Essentially, Diderot is pointing out the harsh, sometimes uncomfortable nature of absolute moral purity, which can make one alienated or unloved.

Diderot’s statement reflects a tension between the ideal of virtue and the practical realities of human nature. While society may speak highly of moral integrity, in practice, it often rewards self-interest, pragmatism, or compromise. The idea that "you've got to keep your feet warm" is a metaphor for staying grounded and engaged with the world, implying that a strict adherence to virtue might prevent someone from engaging in the more practical, human side of life. For Diderot, this suggests that to survive or thrive, one must find a balance between virtue and the demands of the world around them.

The quote also conveys a cynical view of human nature, indicating that people are more likely to embrace what benefits them personally rather than what is morally right or virtuous. Diderot was known for his skepticism about traditional values and his advocacy for reason and pragmatism in both personal and political life. His view of virtue here is not just about individual morality but also a critique of societal norms that often favor convenience over moral high ground.

Originating from the philosophical climate of the Enlightenment, this quote reflects Diderot's broader philosophical beliefs, which challenged established institutions like the church and monarchy. As a key figure in the Encyclopédie, Diderot was deeply concerned with the practical application of reason and ethics in society. His writing often explored the tension between ideals and the realities of human behavior, and this quote encapsulates his belief that virtue, while admirable, can sometimes lead to personal and social isolation.
