Glassmaking; Technology "...it might contribute to dispose us to a kinder regard for the labours of one another, if we were to consider from what unpromising beginnings the most useful productions of art have probably arisen. Who, when he saw the first sand or ashes, by a casual intenseness of heat, melted into a metalline form, rugged with excrescences, and clouded with impurities, would have imagined, that in this shapeless lump lay concealed so many conveniences of life, as would in time constitute a great part of the happiness of the world? Yet by some such fortuitous liquefaction was mankind taught to procure a body at once in a high degree solid and transparent, which might admit the light of the sun, and exclude the violence of the wind; which might extend the sight of the philosopher to new ranges of existence, and charm him at one time with the unbounded extent of the material creation, and at another with the endless subordination of animal life; and, what is yet of more importance, might supply the decays of nature, and succour old age with subsidiary sight. Thus was the first artificer in glass employed, though without his own knowledge or expectation. He was facilitating and prolonging the enjoyment of light, enlarging the avenues of science, and conferring the highest and most lasting pleasures; he was enabling the student to contemplate nature, and the beauty to behold herself."

Memory; Technology "We do not know in what either reason or instinct consists, and therefore cannot tell with exactness how they differ; but surely he that contemplates a ship and a bird's nest will not be long without finding out that the idea of the one was impressed at once, and continued through all the progressive descents of the species, without variation or improvement; and that the other is the result of experiments compared with experiments, has grown, by accumulated observation, from less to greater excellence, and exhibits the collective knowledge of different ages and various professions. "Memory is the purveyor of reason, the power which places those images before the mind upon which the judgment is to be exercised, and which treasures up the determinations that are once passed, as the rules of future action, or grounds of subsequent conclusions." Johnson: Rambler #41 (August 7, 1750) Link 937. Technology "It may sometimes happen, that the greatest efforts of ingenuity have been exerted in trifles; yet the same principles and expedients may be applied to more valuable purposes, and the movements, which put into action machines of no use but to raise the wonder of ignorance, may be employed to drain fens or manufacture metals, to assist the architect or preserve the sailor."
