I presume that the sanguine temperament itself and the disturbing influence end in a mentally accomplished finish; a possibly dangerous man, probably dangerous if unselfish. In selfish men caution is as secure an armour for their foes as for themselves. What I think of on this point is, when self is the fixed point the centripetal force is balanced with the centrifugal; when duty, a cause, etc., is the fixed point, the latter force is paramount, and only accident or a series of accidents can balance it.
