Gottlob Frege (1848-1925)
Inspired by Leibniz, Frege attempts in this book to create a universally valid formal language (modelled in accordance with arithmetic). Frege realises that the use of clear and uniform notation can massively increase the intellectual power of mankind.
In the preface he explains that the ‘inadequacy’ of ordinary language proved to be an obstacle in his logic project.
“If it is one of the tasks of philosophy to break the domination of the word over the human spirit by laying bare the misconceptions that through the use of language often almost unavoidably arise concerning the relations between concepts and by freeing thought from that with which only the means of expression of ordinary language, constituted as they are, saddle it, then my ideography, further developed for these purposes can become a useful tool for the philosopher”
