Note 3 — Chapter II · OF THE BIRTH OF LOVE
Cecil N. Sidney Woolf translation
The coup de foudre (thunderbolt from the blue), as it was called in the novels of the seventeenth century, which disposes of the fate of the hero and his mistress, is a movement of the soul, which for having been abused by a host of scribblers, is experienced none the less in real life. It comes from the impossibility of this defensive manoeuvre. The woman who loves finds too much happiness in the sentiment, which she feels, to carry through successful deception: tired of prudence, she neglects all precaution and yields blindly to the passion of loving. Diffidence makes the coup de foudre impossible.
