(from ἀπός, omnis, and γράφω, scribo), the art of writing on any subject whatsoever, 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 and absurd, whilst the practicability of it is as strenuously contended for by others. Hints respecting such a system of writing as might be understood by all mankind are to be met with in the writings of many eminent philosophers; but the attempt has signally failed, even in the hands of a Leibnitz, a Kircher, a Becher, and a Wilkins. Kant is clearly 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.
