“Ultimately poetic thought is interpretive.”

On the Uses and Transformations of Linear Algebra (1875)
Context: The familiar proposition that all A is B, and all B is C, and therefore all A is C, is contracted in its domain by the substitution of significant words for the symbolic letters. The A, B, and C, are subject to no limitation for the purposes and validity of the proposition; they may represent not merely the actual, but also the ideal, the impossible as well as the possible. In Algebra, likewise, the letters are symbols which, passed through a machinery of argument in accord ance with given laws, are developed into symbolic results under the name of formulas. When the formulas admit of intelligible interpretation, they are accessions to knowledge; but independently of their interpretation they are invaluable as symbolical expressions of thought. But the most noted instance is the symbol called the impossible or imaginary, known also as the square root of minus one, and which, from a shadow of meaning attached to it, may be more definitely distinguished as the symbol of semi-inversion. This symbol is restricted to a precise signification as the representative of perpendicularity in quaternions, and this wonderful algebra of space is intimately dependent upon the special use of the symbol for its symmetry, elegance, and power.

Context: Not to feel elevated on an occasion like the present, by this noble, this magnificent testimony of approbation of my friends, is not in human nature — at all events, it is not in my nature; but if any overweaning self-complacency might arise, and mix itself with my feelings at this moment, there is one consideration which would suffice to set it at rest for ever... The assembly, magnificent as it is, comprising in itself, as it does, the elite of everything that is illustrious in rank, talent, wealth, in the metropolis — this very assembly is a proof of the justice to which I have adverted I should be weak indeed, if I supposed that all this glorious array has reference to myself. No; it has reference to a far higher and more dignified object. I am but as one drop in the ocean. Every man of science will feel quite as much a sharer in the honors of the day, will feel quite as much distinguished by this assembly as I can be; for when, ere this, would it have been possible to collect together such an assembly as is around me to do honor to science, place it n preeminence, and crown it with distinction? This is, indeed, a new era — this is a memorable day for science, and every man who regards truth for its own sake will feel that on this occasion the eyes of the country are on him, and that England expects every man to do his duty! By that I have been able to accomplish in Africa, I have been amply rewarded; but I stand here not so much for anything of this nature, but as the representative of a class that is distinguished — of a principle which is triumphant; and I hope we shall never allow ourselves to forget the infinitely higher and more important circumstance, that it is the great truths of science, that it is the interpretation of God's great book of nature, and not the men who interpret these pages, that are the ultimate objects of all this praise.
