Here is a taster:
No wonder self-knowledge is rare, when so few take pains to acquire it. There are few even who honestly desire it. There are but few men in the world who desire painful things, however salutary they may be; and self-knowledge is both painful in the acquisition and painful in the possession. It is incredible how little honesty there is amongst religious people in religious matters.... Yet almost everyone claims to be preferring God before all things. What a mass of unwholesome delusion then must the religious world be! It is. A supernatural formalism outside with natural principles of action inside, and a thoroughly natural system, or rather quackery, of spiritual direction to keep things comfortable and respectable, - alas! it were devoutly to be wished that this definition embraced less than it does.
Is not life at every turn making unpleasant revelations of self? But they are revelations, and that is noteworthy. Yet what sort of wisdom is it for man to shun these revelations, because they disquiet him, when it will so concern him in the day of judgement to have known them? A spiritual life without a very large allowance of disquietude in it, is no spiritual life at all. It is but a flattering superstition of self-love.
