Pride = loneliness = outer darkness. Pride leads to ambition, to partiality, inability to judge oneself aright, and so to stupidity. Every proud man is stupid in his judgments, even if nature has endowed him with the mind of a genius. Conversely, the humble man is wise even though he may not be ‘clever,’ for the essence of wisdom – a feeling for Truth and humility in its presence – is accessible to him.
