Enlightenment is man’s release from his self-incurred tutelage. Tutelage is man’s inability to make use of his understanding without direction from another . . . "Dare to think! Have the courage to use your own reason!" is therefore the motto of the Enlightenment.
Who must we thank for this bit of eloquent magniloquence on behalf of "reason"? Is it Rand? Is it Peikoff? Is it perhaps Binswanger? Or is it some other Objectivist-sympathizing worthy? Can anyone guess this without cheating?
