For madam, I love not to be constrained to love; for love must arise of the heart, and not by no constraint.
Lancelot to Guinevere, 826
Le Morte D’Arthur
After the body of Elaine (the Fair Maiden of Astolat) arrives, Lancelot is confronted by Guinevere about his guilt in her death. She accuses him of not loving Elaine, and hence causing her death. This reply both confirms the all-consuming power of love and Lancelot’s devotion to Guinevere. He is subtly reminding her that love cannot be controlled, and that he remains devoted to her not by choice but by love. However, he also reveals unwittingly that it has power beyond the lover’s desires. He never meant to destroy King Arthur’s kingdom, but his all-powerful love for Guinevere required as much, and so this answer serves as foreshadowing. King Arthur approves of Lancelot’s statement, though he misses its subtlety.
