Nel portale della Digital Library dell’Università di Pittsburgh trovate i Frank Plumpton Ramsey Papers. É la collezione dei manoscritti scritti dal 1920 al 1930 che documentano il pensiero del logico e matematico inglese. Vi trovate le bozze di due dei lavori più importanti di Ramsey: The Foundations of Mathematics e On a Problem of Formal Logic, ma potete scorrere a video la copia personale del filosofo con le annotazioni del Tractatus of Wittgenstein e le osservazioni sul concetto di infinito che potrebbero essere state dettate dallo stesso Wittgenstein.
There is a long outline of the Tractatus Logico-Philosophicus, apparently prepared for discussions with Wittgenstein. Other notes deal with various aspects of Wittgenstein’s philosophy, logical theory, foundations of mathematics, the infinite, visual space, and solipsism. They bear headings like “Meaning,” “Reconsiderations of Causality, Probability,” “First Philosophy,” and “Existential Judgements.”
“Ramsey’s manner of organizing his material is not known nor are dates included for most of the documents, however, the material begins with his arrival at Cambridge and runs until his death, hence it all falls between 1920 and 1930. The papers have been kept in the order in which they were received. This guide attempts to provide information on the material based on this organization, due to the number of scholarly publications that have previously been published using this order”.
