"But every man feels in his heart that [...] the ultimate idea of a world is not bad or even neutral; staring at the sky or the grass or the truths of mathematics or even a new-laid egg, he has a vague feeling like the shadow of that saying of the great Christian philosopher, St. Thomas Aquinas, “Every existence, as such, is good.” On the other hand, something else tells him that it is unmanly and debased and even diseased to minimise evil to a dot or even a blot. He realises that optimism is morbid. It is if possible even more morbid than pessimism."
