Context

“Mulciber in Trojam, pro Troj stabat Apollo; “Vulcan against, for Troy Apollo stood;” when are we to expect that they will be agreed? We are nearer neighbours to ourselves than whiteness to snow, or weight to stones. If man do not know himself, how should he know his force and functions? It is not, perhaps, that we have not some real knowledge in us; but ‘tis by chance; forasmuch as errors are received into our soul by the same way, after the same manner, and by the same conduct, it has not wherewithal to distinguish them, nor wherewithal to choose the truth from falsehood.” source
