A science is therefore nothing but a well-constructed language. What then are the marks of a good language ? In the first place, it must be simple, so that the mind may not be overwhelmed by the signs, which it should be able to manipulate with ease. What would a man do in whose language there were a hundred different words for the first hundred numbers ? In the second place, the signs must be rigorously determined. Their meaning must be exact, unique, and well defined. Lastly (and this quality... is implied in and implies the two others), a language must be formed according to the laws of analogy. The words, when analysed, must correspond to the elementary ideas they express. It is only on this condition that language can be a guide to the mind, LANGUAGE 223 or that one sign can lead to another according to the laws of analysis. " The whole art of reasoning, like the whole art of speaking, may be reduced to analogy " (Langue des calculs, Pref. ). Everything depends on the order. One expression leads to another and truths are followed by truths when nothing intervenes.
