against some light adroit Man of Theory, all equipt with clear logic, and able anywhere to give you Why for Wherefore! The adroit Man of Theory, so light of movement, clear of utterance, with his bow full-bent and quiver full of arrow-arguments,—surely he will strike down the game, transfix everywhere the heart of the matter; triumph everywhere, as he proves that he shall and must do? To your astonishment, it turns out oftenest No. The cloudy-browed, thick-soled, opaque Practicality, with no logic utterance, in silence mainly, with here and there a low grunt or growl, has in him what transcends all logic-utterance: a Congruity with the Unuttered. The Speakable, which lies atop, as a superficial film, or outer skin, is his or is not his: but the Doable, which reaches down to the World's centre, you find him there!
The rugged Brindley has little to say for himself; the rugged Brindley, when difficulties accumulate on him, retires silent, 'generally to his bed;' retires 'sometimes for three days together to his bed, that he may be in perfect privacy there,' and ascertain in his rough head how the difficulties can be overcome. The ineloquent Brindley, behold he has chained seas together; his ships do visibly float over valleys, invisibly through the hearts of mountains; the Mersey and the Thames, the Humber and the Severn have shaken hands: Nature most audibly answers, Yea! The Man of Theory twangs his full-bent bow: Nature's Fact ought to fall stricken, but does not: his logic-arrow glances from it as from a scaly dragon, and the obstinate Fact keeps walking its way. How singular! At bottom, you will have to grapple closer with the dragon; take it home to you, by real faculty, not by seeming faculty; try whether you are stronger, or it is stronger. Close with it, wrestle it: sheer obstinate toughness of muscle; but much more, what we call toughness of heart, which will mean persistence hopeful and even desperate, unsubduable patience, composed candid openness, clearness of mind: all this shall be 'strength' in wrestling your dragon; the whole man's real strength is in this work, we shall get the measure of him here.
