First, self-knowledge. The physician must know him-
self and understand the mental state of his patient. Error
found out is two-thirds destroyed, and the last third
pierces itself, for the remainder only stimulates and gives [15]
scope to higher demonstration. To strike out right and
left against the mist, never clears the vision; but to lift
your head above it, is a sovereign panacea. Mental dark-
ness is senseless error, neither intelligence nor power, and
its victim is responsible for its supposititious presence. [20]
