Education in its richest sense means a drawing out of the abilities. (e-ducere, Latin, to lead out). The control of a mind by an educator is not bad for the mind's owner, anymore than the control of an intersection by a traffic light is. A good educator demonstrates the necessary control and then returns control to the owner, in the process drawing out and clarifying the individual's own abilitiy to reason about a subject.

This is a world away from the authoritarian version of schooling, which is to shove data into a mind as though into some box, and grade it on its ability to spout out the same information.

The word control is over-burdened with baggage to the point where all control seems wicked or invasive. But good control, such as (for example) a doctor prescribing a full and effective course of antibiotics, is not harmful, when it is subscribed to freely.
