Abstract
In the Pensées, Pascal uses the astonishing phrase “the reality of things” to designate, not the actual existence of things, but the being-thing of all things (in accordance with the meaning of the Latin realitas rerum). It will be established that with this phrase, although it is of Cartesian origin, the analysis of “Disproportion of Man” aims at a criticism of the Cartesian ratio formalis infiniti sive infinitas, which Pascal shows not to be suitable to think God, but only to describe and name nature asthe totality of thinkable objects.
