The mind cannot long play the heart's role.

In the human heart new passions are forever being born; the overthrow of one almost always means the rise of another.

Everyone praises his heart, none dare praise their understanding.

In the human heart there is a ceaseless birth of passions, so that the destruction of one is almost always the establishment of another.

The head does not know how to play the part of the heart for long.

We cannot possibly imagine the variety of contradictions in every heart.

The mind is always the patsy of the heart.

Every one speaks well of his own heart, but no one dares speak well of his own mind.

Imagination does not enable us to invent as many different contradictions as there are by nature in every heart.
