Theory and Practice — Watt and Telford
James Watt was a highly accomplished theorist, on every point on which he worked; yet his name has been frequently cited, as a proof that theory could be dispensed with. And his career, when compared with that of Telford, will illustrate theory applied to practice, as distinguished from practice alone, however acute. It is impossible to contemplate the career of Telford without a feeling of high interest, created by the comparison of his apparently inadequate education with his startling successes. Looking at the individual himself, there is everything for his age to admire; and as long as his structures last, each of them is the monumentum, but not ære perennius. The time will come when his name shall be like that of the builder of the old London bridge, who was, no doubt, the Telford of the day,—a stimulus to his contemporaries, useful and honoured, but not the remembered of succeeding ages. On the other hand, the discoveries of Watt, though equally startling in what is called the practical point of view, have the mind of the discoverer impressed upon them, and have been, and must be, the guide of his successors, not merely to repetitions of what he did himself, but to the enlargement of ideas, and the conversion of principles into forms useful in art. Take away the honourable qualities which enabled the two men to outstrip their contemporaries, each in his line; qualities which are the properties of the individual minds, and consider what is left, namely their modes of proceeding: consider the effect of these two modes on men in general, and there is nothing in that of Telford which would raise a workman above a workman; while in that of Watt there is the vital principle to which we owe all the mechanical triumphs of civilization, and all the theoretical successes of philosophy.—Penny Cyclopædia.
