Person: Peirce (2), Charles S.
Charles Peirce was an eccentric American mathematician whose most important work was on philosophy.
Mathematical Profile (Excerpt):
- We note that this surname is pronounced "Purse".
- Charles was born into a leading American household.
- In many ways this upbringing produced the genius that Charles displayed but it also gave Charles problems of fitting in, which meant that his life was a difficult one.
- By the age of twelve Charles was reading standard university level texts on logic, and in the following year he began reading Immanuel Kant's Critique of Pure Reason.
- He remained greatly influenced by Kant throughout his life.
- He entered Harvard College in 1855 and graduated four years later with an A.B., continuing to study there at graduate level for a year.
- He received a Master's degree from Harvard in 1862 and then a Sc.B. with distinction from the Lawrence Scientific School in 1863.
- Peirce now undertook a range of different scientific studies.
- He had studied species classification with Louis Agassiz, a Harvard zoologist.
- He gave the Harvard lectures on The Logic of Science in the spring of 1865 and the Lowell Institute lectures on The Logic of Science; or Induction and Hypothesis in the latter part of 1866.
- He was elected to the American Academy of Arts and Sciences on 30 January 1867, then from October 1869 to December 1872 he conducted research in astronomy as an assistant at Harvard Observatory.
- Throughout this time he continued research in geodesy for the U.S. Coast Survey, and he was sent to Europe by the Survey from June 1870 to March on the following year.
- He continued to progress through the ranks at the U.S. Coast Survey being put in charge of pendulum experiments in November 1872, then promoted to assistant in December of that year.
- The main task that Peirce carried out in his geodetic work for the U.S. Coast Survey was to measure the force of gravity at various sites both in the United States and abroad.
- His other task was to use the data from the results of his experiments to determine the shape of the earth.
- As part of this work he made further trips to Europe, from April 1875 to August 1876, and again for three months from September 1877.
- For a while Peirce's career continued to move forward.
- He was elected to the National Academy of Sciences (United States) in April 1877 and published the results of his earlier research in astronomy in a book Photometric Researches (1878).
- Although his work had been wide ranging in the sciences, he had always been interested in philosophy and logic and, in 1879, he was appointed as Lecturer in Logic in the Department of Mathematics at Johns Hopkins University.
- Sylvester was Head of Mathematics at Johns Hopkins University at this time and for a while things went well for Peirce.
- He became interested in the Four Colour Problem, and problems of knots and linkages studied by Kempe.
- However by now Peirce was living with Juliette Froissy Pourtalès, a French gypsy.
- Not wishing to be involved in a scandal, the trustees chose not to renew Peirce's contract.
- Peirce would never hold another academic post.
- Peirce's only steady work was now for the Coast and Geodetic Survey.
- He went to Washington, D.C. to work on data on gravity measurements which had been returned from the Artic.
- He moved to New York City in 1886 and continued on his work for the Survey but he became increasingly at odds with his superiors and worked more and more in isolation.
- The Coast Survey also came under increasing pressure through lack of funding by the government.
- He purchased further land and a farm after he received a small inheritance from a maiden aunt in 1888.
- When he finally submitted his major report on gravity to the U.S. Coastal Survey in 1890 it was rejected for publication unless he made major revisions.
- When nothing further was received from him by the end of 1891 the Survey asked for his resignation.
- Peirce now had no income at all.
- His dramatic manner, his reckless disregard of accuracy in what he termed 'unimportant details', his clever newspaper articles describing the meetings of our young Society interested and amused us all.
- He was always hard up, living partly on what he could borrow from friends, and partly on what he got from odd jobs such as writing book reviews ...
- He was equally brilliant, whether under the influence of liquor or otherwise, and his company was prized by the various organisations to which he belonged; and he was never dropped from any of them even though he was unable to pay his dues.
- Shortly afterwards Miss Scott contributed to the Bulletin a more factual, sober article upon Cayley's life and work ...
- Much of what Peirce wrote from this time onwards was either rejected for publication, or he failed to complete the project.
- In the first category there is How to Reason (rejected by two publishers in 1894), and New Elements of Mathematics (rejected in 1895).
- In the second category is Search for a Method (announced in 1893 but not completed), The Principles of Philosophy (twelve volumes announced in 1894 but not completed), and The History of Science (announced in 1898 but not completed).
- Peirce today is most famous as a philosopher although it is fair to say that this fame only came late.
- In 1877 and 1878 Peirce published six essays on Illustrations of the Logic of Science in the Popular Science Monthly.
- The first two of these essays were The Fixation of Belief and How to Make Our Ideas Clear.
- It was in the second of these that he set out his pragmatic philosophy for which he is best known today.
- Then, our conception of these effects is the whole of our conception of the object.
- When he said that the whole meaning of a (clear) conception consists in the entire set of its practical consequences, he had in mind that a meaningful conception must have some experiential "cash value," capable of being specified as some sort of collection of possible empirical observations under specifiable conditions.
- Peirce insisted that the entire meaning of a meaningful conception consisted in the totality of such specifications of possible observations.
- It was twenty years after he published these ideas on pragmatism that, through the work of William James, Peirce began to gain the credit for his ideas.
- Peirce lectured on Pragmatism at Harvard in March to May of 1903 and published a series of essays explaining his ideas in The Monist in 1905.
- It is impossible to do justice to the breadth of Peirce's philosophical work in this article.
- Let us just note some further examples.
- He wrote on infinite sets and infinitesimals and argued for the consistency of introducing infinitesimals into the number system.
- He wrote on probability arguing against De Morgan's ideas that probability is a measure of confidence and also arguing against the ideas of Bayes.
- Rather for Peirce probability is the limit of the ratio of observed occurrences over the possible occurrences and the number of observations tend to infinity.
- He also studied universal categories and for him almost everything split into three categories or triads.
- On the mathematical side, coming out of his work for the Coast Survey, we mention that he was interested in conformal map projections where he invented a quincuncial map projection using elliptic functions.
- We have already indicated that Peirce was a somewhat unusual character.
- Peirce died of cancer at his home at Arisbe, Milford, Pennsylvania.
Born 10 September 1839, Cambridge, Massachusetts, USA. Died 19 April 1914, Milford, Pennsylvania, USA.
