Judge every word and deed which are according to nature to be fit for thee; and be not diverted by the blame which follows from any people, nor by their words, but if a thing is good to be done or said, do not consider it unworthy of thee. For those persons have their peculiar leading principle and follow their peculiar movement; which things do not thou regard, but go straight on, following thy own nature and the common nature; and the way of both is one.
