III. And now granting that a student has started with good intentions and is well informed about the direction where profit lies, still have we any assurance that he will push those intentions with a fair degree of tenacity through the distractions which beset his daily path? We need, indeed we must have, a third class of helpful limitations which may secure the persistent adhesion of our student to his chosen line of work. Probably this class of limitations is the most important and complex of all. To yield a paying return, study must be stuck to. A decision has little meaning unless the volition of to-day brings in its train a volition to-morrow. Self-direction implies such patient continuance in well-doing that only after persistence has become somewhat habitual can choice be called mature. To establish onward-leading habits, therefore, should be one of the chief objects in devising limitations of election. Only we must not mistake; we must look below the surface. Mechanical diligence often covers mental sloth. It is not habits of passive docility that are desirable, habits of timidity and uncriticising acceptance. Against forming these pernicious and easily acquired habits, it may be necessary even to erect barriers. The habit wanted is the habit of spontaneous attack. Prescription deadened this vital habit; it mechanized. His task removed, the student had little independent momentum. Election invigorates the springs of action. Formerly I did not see this, and I favored prescribed systems, thinking them systems of duty. That absence of an aggressive intellectual life which prescribed studies induce, I, like many others, mistook for faithfulness. Experience has instructed me. I no longer have any question that for the average man sound habits of steady endeavor grow best in fields of choice. Emerson's words are words of soberness:-- He that worketh high and wise Nor pauses in his plan, Will take the sun out of the skies Ere freedom out of man.
