Gargoyles were the complement to saints; Leonardo's caricatures were complementary to his untiring search for ideal beauty. And gargoyles were the expression of all the passions, the animal forces, the Caliban gruntings and groanings which are left in human nature when the divine has been poured away. Leonardo was less concerned than his Gothic predecessors with the ethereal parts of our nature, and so his caricatures, in their expression of passionate energy, merge imperceptibly into the heroic.

Fine colour implies a unified relationship, in which each part is subordinate to the whole, and the transitions between them are felt to be as precious and beautiful as the colours themselves. In fact, the colours themselves must be continuously modified and broken as part of the transition.

Sweeping, confident articles on the future seem to me, intellectually, the most disreputable of all forms of public utterance.

I believe order is better than chaos, creation better than destruction. I prefer gentleness to violence, forgiveness to vendetta. On the whole I think that knowledge is preferable to ignorance, and I am sure that human sympathy is more valuable than ideology.
