(from παίζω, all, and γράφω, I write), the imaginary art of writing so as to be universally understood by all nations of the earth. The idea of establishing such a language is deemed by many extremely fanciful, whilst the practicability of it is as strenuously contended for by others. Hints respecting such an universal language are to be met with in the writings of many eminent philosophers; but the attempt has signalily failed, even in the hands of Leibnitz, Kircher, Becher, and Wilkins. Kant is of opinion, however, that such a pasigraphy falls within the limits of possibility; nay, he even prognosticates that it will certainly be established at some future period.
