9.I would like to restore the context of this quotation: “I believe, however, that it would be
possible to devise a further system to enable one to make up the primitive words and their
symbols in such a language so that it could be learnt very quickly. Order is what it needed: all
the thoughts which can come into the human mind must be arranged in an order like the
natural order of the numbers. In a single day one can learn to name every one of the infinite
series of numbers, and thus to write infinitely many different words in an unknown language.
The same could be done for all the other words necessary to express all the other things which
fall within the purview of the human mind. If this secret were discovered I am sure that the
language would soon spread throughout the world. Many people would willingly spend five
or six days in learning how to make themselves understood by the whole human race.
“But I do not think that your author has thought of this. There is nothing in all his propositions
to suggest it, and in any case the discovery of such a language depends upon the true
philosophy. For without that philosophy it is impossible to number and order all the thoughts
of men or even to separate them out into clear and simple thoughts, which in my opinion is
the great secret for acquiring true scientific knowledge. If someone were to explain correctly
what are the simple ideas in the human imagination out of which all human thoughts are
compounded, and if his explanation were generally received, I would dare to hope for a
universal language very easy to learn, to speak, and to write. The greatest advantage of such a
language would be the assistance it would give to men’s
((331))
judgment, representing matters so clearly that it would be almost impossible to go wrong. As
it is, almost all our words have confused meanings, and men’s minds are so accustomed to
them that there is hardly anything which they can perfectly understand.
“I think it is possible to invent such a language” [Philosophical Letters, pp. 5—6].

14.Cf., for example, among many other texts, Monadology 1 to 3 and 51. It is beside the point
both of our project and of the possibilities of our demonstrating from internal evidence the
link between the characteristic and Leibniz’s infinitist theology. For that it would be necessary
to go through and exhaust the entire content of the project. I refer on this point to works
already cited. Like Leibniz when he wishes to recall in a letter the link between the existence
of God and the possibility of a universal script, I shall say here that “it is a proposition that
[we] cannot demonstrate properly without explaining the foundations of the characteristic at
length. . . . But at present, suffice it to remark that the foundation of my characteristic is also
the demonstration of the existence of God, for simple thoughts are the elements of the
characteristic, and simple forms are the source of things. Now I maintain that all simple forms
are compatible among themselves. It is a proposition that I cannot demonstrate properly with-
out explaining the foundations of the characteristic at length. But if it is granted, then it
follows that the nature of God which holds absolutely all simple forms, is possible. Now we
have proved above, that God is, provided He is possible. Therefore He exists. Which had to be
demonstrated.” (Letter to the Princess Elizabeth, 1678) There is an essential connection
between the possibility of the ontological argument and that of the Characteristic.

Concerning Human Understanding, by Alfred Gideon Langley (New York and London, 1896)

universalis et lingua philosophica (London, 1661). On Wilkins cf. supra, Couturat, op. cit.,
and DE, passim. A script or a language of pure institution and of pure arbitrariness cannot
have been invented, as a system, except all at once. It is this that, before Duclos, Rousseau,
and Lévi-Strauss (cf. infra), Leibniz deems probable: “Thus it was the opinion of Golius, a
celebrated mathematician and great linguist, that their language is artificial, i.e. had been
invented all at once by some clever man in order to establish verbal intercourse between the
large number of different nations inhabiting this great country which we call China, although
this language may now be found altered by long use” (III. I. S 1) .
