Who is the most original and the most versatile intellect that the Americas have so far produced? The answer “Charles S. Peirce” is uncontested, because any second would be so far behind as not to be worth nominating. Mathematician, astronomer, chemist, geodesist, surveyor, cartographer, metrologist, spectroscopist, engineer, inventor; psychologist, philologist, lexicographer, historian of science, mathematical economist, lifelong student of medicine; book reviewer, dramatist, actor, short story writer; phenomenologist, semiotician, logician, rhetorician, metaphysician-and, the Sebeoks now add, detective! He was, for a few examples, the first modern experimental psychologist in the Americas, the first mythologist to use a wave-length of light as a unit of measure, the inventor of the quincuncial projection of the sphere, the first known conceiver of the design and theory of an electric switching-circuit computer, and the founder of “the economy of research.” He is the only system-building philosopher in the Americas who has been both competent and productive in logic, in mathematics, and in a wide range of the sciences. If he has had any equals in that respect in the entire history of philosophy, they do not number more than two.
