“ His versatility, eagerness, activity, and humanity; the immense range of his curiosity, in all things physical, moral, or social; his place in science, in theology, in philosophy, and in politics; his peculiar relation to the [French] Revolution, and the pathetic story of his unmerited sufferings, may make him the hero of the eighteenth century. ” ​ — Frederic Harrison, philosopher.
” Ia serbabisa, bersemangat, giat, dan toleran; ia punya rasa ingin tahu yang besar akan berbagai hal: jasmani, moral, atau sosial; ia punya andil dalam sains, teologi, filsafat, dan politik; ia terlibat dalam Revolusi [Prancis], dan ia mengalami penderitaan yang tak sepantasnya ia terima. Semua itu menjadikan dia pahlawan abad kedelapan belas. ” ​ — Frederic Harrison, filsuf.
