Many researchers in the field of Geometric Algebra claim it to be the universal language of mathematics and

physics and so realise Leibniz’s vision. Their claim has some merit. However, Leibniz’s geometry without

number vision was much more ambitious. For example, Leibniz claimed that the geometry would explain the

forms of plants and animals ‘in a few letters.’ Since the discovery of the genetic code, we now know such a code

indeed does exist. However, Geometric Algebra makes no reference to the genetic code, the truly authentic

algebra of Nature. In this paper we work closely with Leibniz’s core concepts, together with a strong Stoicism

influence, and show how his approach to metaphysics and geometric algebra can be made tractable. The end

result is a geometric algebra based on a four-letter alphabet. The four letters are shown to correspond to the

geometric semantics of timelike, lightlike, spacelike, and singular vectors of a geometric algebra. We propose an

exact mapping of these four generic letters to those of the genetic code. Thus, the genetic code is interpreted as

expressing generic geometric organisation based on a Leibniz style geometric algebra rather than being a mere

transcription code as stated in the Central Dogma of biochemistry..
