Selected Articles in Journals & Books

Blank, Andreas. "Dalgarno, Wilkins, Leibniz and the Descriptive Nature of Metaphysical Concepts," in Leibniz and the English-Speaking World, edited by Pauline Phemister and Stuart Brown (Dordrecht: Springer, 2007), pp. 51-61. (The New Synthese Historical Library; v. 62)

Borges, Jorge Luis. "E. S. Pankhurst, Delphos, or the Future of the International Language [review]" (1939), in Selected Non-Fictions, edited by Eliot Weinberger; translated by Esther Allen, Suzanne Jill Levine, and Eliot Weinberger (New York: Viking, 1999), pp. 194-195.

Borges takes up artificial language in later essays and stories. Projects, languages and figures mentioned here are: John Wilkins, Letellier, Volapük (Schleyer), Esperanto, Neutral Idiom, Interlingua (Peano), Dr. Henry Sweet, with a sample sentence in Idiom Neutral.

Borges, Jorge Luis. "Ramón Llull's Thinking Machine" (1937), in Selected Non-Fictions, edited by Eliot Weinberger; translated by Esther Allen, Suzanne Jill Levine, and Eliot Weinberger (New York: Viking, 1999), pp. 155-159.

Borges assesses Llull's thinking machine (composed of movable disks enabling myriad combinations of elementary ideas) useless, an absurdity for philosophical purposes but perhaps useful as a literary device. Borges adduces two diagrams, the first a diagram of divine attributes, the second, of Llull's thinking machine. It unworkability is illustrated by Borges using one of his favorite symbols, a tiger. The device is ridiculed in Swift's Gulliver's Travels. Of the first diagram, Borges suggests that the theological subject matter would not be rewarding today.

We now know that the concepts of goodness, greatness, wisdom, power, and glory are incapable of engendering an appreciable revelation. We (who are basically no less naive than Llull) would load the machine differently, no doubt with the words Entropy, Time, Electrons, Potential Energy, Fourth Dimension, Relativity, Protons, Einstein. Or with Surplus Value, Proletariat, Capitalism, Class Struggle, Dialectical Materialism, Engels. [157]

Note: Bibliography is largely limited to books in English covering secondary literature rather than primary sources. Though often treated together historically, artificial philosophical languages (a.k.a. ''universal character") are different in nature and purpose from constructed languages like Esperanto based on ethnic languages and intended as universal auxiliary languages.

Library of Congress Subject Headings for this topic are "Language, Universal" and "Languages, Artificial". For fictional and imaginary languages see "Imaginary languages".
