I speak not of the hypocrite, nor dream of meant deceptions,
But of that quick unconscious change, whereof the best know most.
For mind hath its influence on mind; and no man is free but when alone;
Yea, let a dog be watching thee, its eye will tend to thy restraint:
Self-possession cannot be so perfect, with another intellect beside thee,
It is not as a natural result, but rather the educated produce:
The presence of a second spirit must control thine own,
And throw it off its equipoise of peace, to balance by an effort.
The common minds of common men know of this but little;
What then? they know nothing of themselves: I speak to those who know.
