Helmuth Plessner

Plessner developed a philosophical biology and anthropology which amounted to a hermeneutics of nature. According to Plessner, life expresses itself, and part of this expression is in terms of sentient lifeforms. In expressing itself through the human senses, it provides the (material) a priori constituents of perception (to replace Kant's cognitive idealism of a priori categories and intuitions produced by transcendental subjectivity as the filter through which we spontaneously order experience of the world). In other words, the formal qualities that make up our consciousness a priori — given as the conditions through which we experience things — conditions such as time, space, causality and number, and, indeed, the laws of physics, however we may then conceptualize them, are given to us both in our own physical nature, and in the physical nature of the environments we inhabit, through our growth from and interactions within these environments.

From Husserl and Scheler, Plessner adapted the idea of the intentionality of consciousness away from the need for a transcendental ego or apperception and instead grounds it in the behaviour (in the broadest sense of the term) of environmentally interactive organisms as a realizing of borders that represents the point where the impulses or growth of organisms meet with their environments, are realized in the act of self-positioning. These are the scopes of action and understanding that define consciousness and which at the same time ground it in the material world of nature. In terms of plants, their self-expression is utterly open—their borders are defined by only very simple forms of feedback, and the plant has no ability to express intentional preferences regarding its environment; animals, on the other hand, are aware of their own borders and are constantly pressed back within them, thus exhibiting a closed kind of intentionality trapped by its own borders, this is the limit of their expression; finally, humans alternate between open and closed intentionality — we are these borders, but also, we have them, and the limits of these borders of human action, influence and being Plessner described as the eccentricity of human intentionality in its environmental relations and determination. For Plessner, our own subjectivity can be understood in terms of the expressive a priori in nature, and our experience of and relationship to it.
