Frederik Wellmann
1903
A. MS. notebook
A liberal education in a hundred lessons: fifty lessons devoted to the teaching of some small branch of knowledge. Of the remaining fifty lessons, thirtysix were to be devoted to logic. Lectures begin with a discussion of the different kinds of mathematics. Dichotonic and trichotonic mathematics. Logic of relatives. Incident involving Sylvester, who claimed that mathematical work shown him by CSP, who, in turn, suspected that his work reduced to Cayley's Theory of Matrices, was really nothing more than Sylvester's umbral notation. Later CSP discovers, with some satisfaction, that what Sylvester called "my umbral notation" had originally been published in 1693 by Leibniz. CSP's bitterness revealed in his remark that he can find a more comfortable way of ending his days, if nobody is interested in his efforts to gather together the scattered outcroppings of his work in logic for the purpose of a more systematic presentation of it.
