Daniel Everett writes:

The roll of scientists born in the 19th century is as impressive as any century in history. Names such as Albert Einstein, Nikola Tesla, George Washington Carver, Alfred North Whitehead, Louis Agassiz, Benjamin Peirce, Leo Szilard, Edwin Hubble, Katharine Blodgett, Thomas Edison, Gerty Cori, Maria Mitchell, Annie Jump Cannon and Norbert Wiener created a legacy of knowledge and scientific method that fuels our modern lives. Which of these, though, was ‘the best’?

Remarkably, in the brilliant light of these names, there was in fact a scientist who surpassed all others in sheer intellectual virtuosity. Charles Sanders Peirce (1839-1914), pronounced ‘purse’, was a solitary eccentric working in the town of Milford, Pennsylvania, isolated from any intellectual centre. Although many of his contemporaries shared the view that Peirce was a genius of historic proportions, he is little-known today. His current obscurity belies the prediction of the German mathematician Ernst Schröder, who said that Peirce’s ‘fame [will] shine like that of Leibniz or Aristotle into all the thousands of years to come’.

Some might doubt this lofty view of Peirce. Others might admire him for this or that contribution yet, overall, hold an opinion of his oeuvre similar to that expressed by the psychologist William James on one of his lectures, that it was like ‘flashes of brilliant light relieved against Cimmerian darkness’. Peirce might have good things to say, so this reasoning goes, but they are too abstruse for the nonspecialist to understand. I think that a great deal of Peirce’s reputation for obscurity is due, not to Peirce per se, but to the poor organisation and editing of his papers during their early storage at and control by Harvard University (for more on this, see André de Tienne’s insightful history of those papers).

Such skepticism, however incorrect, becomes self-reinforcing. Because relatively few people have heard of Peirce, at least relative to the names above, and because he has therefore had a negligible influence in popular culture, some assume that he merits nothing more than minor fame. But there are excellent reasons why it is worth getting to know more about him. The leading Peirce scholar ever, Max Fisch, described Peirce’s intellectual significance in this fecund paragraph from 1981:

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 [and] metaphysician … He was, for a few examples, … the first metrologist 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 sciences. If he has had any equals in that respect in the entire history of philosophy, they do not number more than two. [Continue reading…]
