text: When such men as these were disturbing the world, they were themselves disturbed – like cyclones that whirl together what they have seized, but which are first whirled themselves and can for this reason rush on with all the greater force, having no control over themselves; hence, after causing such destruction to others, they feel in their own body the ruinous force which has enabled them to cause havoc to many. You need never believe that a man can become happy through the unhappiness of another. We must unravel all such cases as are forced before our eyes and crammed into our ears; we must clear out our hearts, for they are full of evil talk. Virtue must be conducted into the place these have seized, – a kind of virtue which may root out falsehood and doctrines which contravene the truth, or may sunder us from the throng, in which we put too great trust, and may restore us to the possession of sound opinions. For this is wisdom – a return to Nature and a restoration to the condition from which man's errors have driven us. It is a great part of health to have forsaken the counsellors of madness and to have fled far from a companionship that is mutually baneful.
