It constructs for the ear the instruments by which it is educated, and sounds them in its hearing till its powers are trained to the full.
It plucks for the nostril the flower which it longs to smell, and distills for it the fragrance which it covets.
As for the tongue, if it had not the hand to serve it, it might abdicate its throne as the “Lord of Taste.” In short, the organ of touch is the minister of its sister senses, and, without any play of words, is the handmaid of them all.
And if the hand thus munificently serves the body, not less amply does it give expression to the genius and the wit, the courage and the affection, the will and the power of man. Put a sword into it, and it will fight for him; put a plow into it, and it will till for him; put a harp into it, and it will play for him; put a pencil into it, and it will paint for him; put a pen into it, and it will speak for him, plead for him, pray for him.
What will it not do? What has it not done? A steam engine is but a larger hand, made to extend its powers by the little hand of man! An electric telegraph is but a long pen for that little hand to write with! All our huge cannon and other weapons of war, with which we so effectually slay our brethern, are only Cain’s hand made bigger, and stronger, and bloodier!
What, moreover, is a ship, a railway, a lighthouse, or a palace—what, indeed, is a whole city, a whole continent of cities, all the cities of the globe, nay, the very globe itself, in so far as man has changed it, but the work of that giant hand, with which the human race, acting as one mighty man, has executed its will!
What an instrument for good it is! What an instrument for evil! and all the day long it never is idle. There is no implement which it cannot wield, and it should never in working hours be without one. It is the one universal craftsman. For the queen’s hand there is the scepter, and for the soldier’s hand the sword; for the carpenter’s hand the saw, and for the smith’s hand the hammer; for the farmer’s hand the plow; for the miner’s hand the pick; for the sailor’s hand the oar; for the painter’s hand the brush; for the sculptor’s hand the chisel; for the poet’s hand the pen; and for the woman’s hand the needle.
For each willing man and woman there is a tool they may learn to handle; for all there is the command, “Whatsoever thy hand findeth to do, do it with all thy might.”
Such are the five entrance-ways of knowledge, which John Bunyan quaintly styles Eye-gate, Ear-gate, Nose-gate, Mouth-gate, and Feel-gate.
