Nicolas Caussin (1583–1651) was a French Jesuit, a theorist of the passions.
His treatise, The Holy Court Fourth Tome, was published in 1638.
This work gives a Christianized account of what he calls the four principal passions: Love, Desire, Anger, and Envy, as well as many variants and subgenres of these types.
The intent of the work is to instruct the proper means for controlling these affects.
