Similar plane and solid numbers are those which have their sides proportional. 22. A perfect number is that which is equal to the sum its own parts. As can be seen, these axioms state clearly what numbers are and how they form a closed system. There is no room for variation or interpretation here. Euclid’s approach remained the basic blueprint for the development of formal mathematical systems, until other geometries and the calculus came onto the scene much later. These expanded the reach of formal Euclidean mathematics to include different numerical and spatial concepts.

The search for universal rules and language-speciﬁc adaptations of these rules (known as parameters) continues to guide the overall research agenda of generative linguistics to this day and, by extension, of any formal approach based on the syntax hypothesis. Chomsky proclaimed that the primary task of the linguist was to describe the native speaker’s “ideal knowledge” of a language, which he called an unconscious linguistic competence, basically substituting this term for Saussure’s term of langue.

As discussed above, in linguistics the ﬁrst attempt to articulate a formal theory of language, using ideas from mathematics was the one by Chomsky in 1957. Chomsky was inﬂuenced initially by his teacher, the American structuralist Zellig Harris (1951) who, like the Port-Royal grammarians, suggested that linguists should focus on sentences as the basic units of language, not on phonemes and words in isolation. As we saw, Chomsky developed this idea into the syntax hypothesis, going on to argue that a true theory of language would have to explain, for instance, why all languages seemed to reveal a similar pattern of constructing complex sentences from more simple ones.
