There is a very permanent truth in the fact that two free persons deliberately tie themselves to a log of wood. And it is the idea of tying oneself to something that runs through all this old amorous allegory like a pattern of fetters. There is always the notion of hearts chained together, or skewered together, or in some manner secured; there is a security that can only be called captivity. That it frequently fails to secure itself has nothing to do with the present point. The point is that every philosophy of sex must fail, which does not account for its ambition of fixity, as well as for its experience of failure. There is nothing to make Orlando commit himself on the sworn evidence of the nearest tree. He is not bound to be bound; he is under constraint, but nobody constrains him to be under constraint. In short, Orlando took a vow to marry precisely as Valentine took a vow not to marry. Nor could any ascetic, without being a heretic, have asserted in the wildest reactions of asceticism, that the vow of Orlando was not lawful as well as the vow of Valentine. But it is a notable fact that even when it was not lawful, it was still a vow. Through all that mediæval culture, which has left us the legend of romance, there ran this pattern of a chain, which was felt as binding even where it ought not to bind. The lawless loves of mediæval legends all have their own law, and especially their own loyalty, as in the tales of Tristram or Lancelot. In this sense we might say that mediæval profligacy was more fixed than modern marriage. I am not here discussing either modern or mediæval ethics, in the matter of what they did say or ought to say of such things. I am only noting as a historical fact the insistence of the mediæval imagination, even at its wildest, upon one particular idea. That idea is the idea of the vow. It might be the vow which St. Valentine took; it might be a lesser vow which he regarded as lawful; it might be a wild vow which he regarded as quite lawless. But the whole society which made such festivals and bequeathed to us such traditions was full of the idea of vows; and we must recognise this notion, even if we think it nonsensical, as the note of the whole civilisation. And Valentine and the valentine both express it for us; even more if we feel them both as exaggerated, or even as exaggerating opposites. Those extremes meet; and they meet in the same place. Their trysting place is by the tree on which the lover hung his love-letters. And even if the lover hung himself on the tree, instead of his literary compositions, even that act had about it also an indefinable flavour of finality.
