An active and energetic mind, if denied liberty, will seek for power: refused the command of itself, it will assert its personality by attempting to control others.

Context

“No less large and powerful is their part, we may assure ourselves, in the lives and feelings of women. Women are schooled into suppressing them in their most natural and most healthy direction, but the internal principle remains, in a different outward form. An active and energetic mind, if denied liberty, will seek for power: refused the command of itself, it will assert its personality by attempting to control others. To allow to any human beings no existence of their own but what depends on others, is giving far too high a premium on bending others to their purposes. [Pg 182] Where liberty cannot be hoped for, and power can, power becomes the grand object of human desire;” source
