But if a natural history perfectly distinct from the analysis of words is indispensable, that is because experience does not reveal the continuity of nature as such, but gives it to us both broken up since there are a great many gaps in the series of values effectively occupied by the variables (there are possible creatures whose place in the grid one can note without ever having had the opportunity to observe them) and blurred, since the real, geographic and terrestrial space in which we find ourselves confronts us with creatures that are interwoven with one another, in an order which, in relation to the great network of taxonomies, is nothing more than chance, disorder, or turbulence.
