equiprimordial
Existing together as equally fundamental ab initio; coöriginal.
If what has been said above on the subject of language and existence has any truth in it, then we must look on the myth as an undifferentiated matrix of meaning. Only later were the various meanings sorted out, but they were all latent in the myth from the beginning. If we may borrow a favourite word of Heidegger, we may say that they are ‘equiprimordial’.
Where it comes from
Coined by John Macquarrie in his 1960 The Scope of Demythologizing as equi- + primordial, translating Martin Heidegger’s German gleichursprünglich.
