A soul in which the type of “free spirit” can attain maturity and completeness had its decisive and deciding event in the form of a great emancipation or unbinding, and that prior to that event it seemed only the more firmly and forever chained to its place and pillar… The great liberation comes suddenly to such prisoners, like an earthquake: the young soul is all at once shaken, torn apart, cast forth — it comprehends not itself what is taking place. An involuntary onward impulse rules them with the mastery of command; a will, a wish are developed to go forward… a mutinous, willful, volcanic-like longing for a far away journey…
Becoming a free spirit, Nietzsche insists, requires learning “to read the riddle of that great liberation” — a liberation the fruition of which he captures in a passage nothing short of transcendent:
You had to become master over yourself, master of your own good qualities. Formerly they were your masters: but they should be merely your tools along with other tools. You had to acquire power over your aye and no and learn to hold and withhold them in accordance with your higher aims… You had to find out the inevitable error in every Yes and in every No, error as inseparable from life, life itself as conditioned by the perspective and its inaccuracy. Above all, you had to see with your own eyes where the error is always greatest: there, namely, where life is littlest, narrowest, meanest, least developed and yet cannot help looking upon itself as the goal and standard of things, and smugly and ignobly and incessantly tearing to tatters all that is highest and greatest and richest, and putting the shreds into the form of questions from the standpoint of its own well being.
