What makes a piece of mathematical economics not only mathematics but also economics is, I believe, this: When we set up a system of theoretical relationships and use economic names for the otherwise purely theoretical variables involved, we have in mind some actual experiment, or some design of an experiment, which we could at least imagine arranging, in order to measure those quantities in real economic life that we think might obey the laws imposed on their theoretical namesakes.

One of the most terrible things about the English education System in Ireland is its ruthlessness...it is cold and mechanical, like the ruthlessness of an immensely powerful engine. A machine vast, complicated... It grinds night and day; it obeys immutable and predetermined laws; it is as devoid of understanding, of sympathy, of imagination, as is any other piece of machinery that performs an appointed task. Into it is fed all raw human material in Ireland; it seizes upon it inexorably and rends and compresses and remoulds...
Patrick Pearse
I was appalled to find that the mathematical notation on which I had been raised failed to fill the needs of the courses I was assigned, and I began work on extensions to notation that might serve. In particular, I adopted the matrix algebra used in my thesis work, the systematic use of matrices and higher-dimensional arrays (almost) learned in a course in Tensor Analysis rashly taken in my third year at Queen's, and (eventually) the notion of Operators in the sense introduced by Heaviside in his treatment of Maxwell's equations.
Kenneth E. Iverson
There is rarely a creative man who does not have to pay a high price for the divine spark of his greatest gifts...the human element is frequently bled for the benefit of the creative element and to such an extent that it even brings out the bad qualities, as for instance, ruthless, naive egoism (so-called "auto-eroticism"), vanity, all kinds of vices-and all this in order to bring to the human I at least some life-strength, since otherwise it would perish of sheer inanition.
Carl Jung
I am willing to believe that my unobtainable sixty seconds within a sponge or a flatworm might not reveal any mental acuity that I would care to call consciousness. But I am also confident [...] that vultures and sloths, as close evolutionary relatives with the same basic set of organs, lie on our side of any meaningful (and necessarily fuzzy) border-and that we are therefore not mistaken when we look them in the eye and see a glimmer of emotional and conceptual affinity.
Stephen Jay Gould
But those rare souls whose spirit gets magically into the hearts of men, leave behind them something more real and warmly personal than bodily presence, an ineffable and eternal thing. It is everlasting life touching us as something more than a vague, recondite concept. The sound of a great name dies like an echo the splendor of fame fades into nothing but the grace of a fine spirit pervades the places through which it has passed, like the haunting loveliness of mignonette.
James Thurber
