Turgot wrote in the calm spirit of an inquirer.

Condorcet spoke with the verve of a prophet.

He was prophesying under the shadow of death.

It is amazing that the optimistic Sketch of a Historical Picture of the Progress of the Human Mind should have been composed when he was hiding from Robespierre in 1793.
[Footnote: Published in 1795.] Condorcet was penetrated with the spirit of the Encyclopaedists, of whom he had been one, and his attitude to Christianity was that of Voltaire and Diderot.

Turgot had treated the received religion respectfully.
