Heidegger’s ‘serious idealism’ aims at capturing the realist impulses of our natural consciousness whilst avoiding a collapse into metaphysical realism. This idealism is best conceived as a form of transcendental empiricism. But we need to distinguish two varieties of transcendental empiricism, corresponding to Heidegger’s early and later work. The latter, transcendental empiricism2, is superior. Here, Heidegger’s ontology of gift gives full, conceptual shape to the two-way dependency between man and world characteristic of transcendental empiricism as a whole. In exemplary forms of inspired experience, marked by the 'animation' of our conceptually-structured natural powers, things call on us in a speech that is their very own. This moves us decisively beyond not only early Heidegger’s transcendental empiricism1 but also the picture of experience presented in McDowell’s Mind and World.

Heidegger argues that for being x to count as ‘alive’ it must satisfy three metaphysical conditions. It must be capable of engaging in active behaviour with a form of intentional directedness that offers to us a “sphere of transposition” into which we can intelligibly “transpose ourselves.” Heidegger’s discussion of these conditions, as they apply to the being of animals, is well-known. But, if his argument is sound, they ought also to apply to the being of plants. Heidegger, unfortunately, does not supply this part of his ontology of life in any systematic detail. However, my thesis is that it is possible to interpret the nature and activities of plants, along the lines of –, and thus to make good on Heidegger’s omission. The key to this reconstruction is a reconceptualization of plant movements as constituted by a form of representationally blind, motor-intentionality.
