Having endowed each animal with its subjective Umwelt that remains impenetrable to others, Uexkull nevertheless claims that all the Umwelten
are penetrable to "Nature's overall plan" (2010, 86).
Simply to generalise the notion of "world" and apply it to both humans and animals would be ontologically deficient in its assumption that animals have environments in exactly the same sense as humans, the only difference being a lower level of complexity in animal Umwelten
. (29) Uexkull's implicit ontological univocity is inadequate from a philosophical standpoint which sees the human being alone as endowed with [TEXT NOT REPRODUCIBLE IN ASCII] and possessed of the related ability to recognise beings as particular things and ultimately simply as beings--beings "as such" and hence as manifestations of being itself.
The types of movement defining these competing Umwelten
are both "implied by the movement" of horses; but the nature of that movement could hardly be more different.

," see Ryan 2014a.
Rather than considering the possibilities of the organism's unfolding development in ways not predictable from its earliest form, or recognising the worldforming implications of Uexkull's Umwelten
theory, Heidegger rejected Driesch's theories of entelechy as 'vitalism' and saw Uexkull's Umwelt as an encircling ring that limits the animal's behaviour.

Merrell contrasts the "semiotically real" with the "actually real," denying that we have access to the latter, and reworks the former concept in terms of species-specific Umwelten
that function as meaning horizons for living systems.
