principle of reason

is the modern techno-scientific principle, simply, that for everything some reason or ground can or must be rendered.

The rest of this chapter will concern the modern epoch as Heidegger conceives it. In Der Satz von Grund [The Principle of Reason] (1957) Heidegger considers a crucial principle of thought, one implicit already in Greek thought, but coming to open expression only in the work of the late seventeenth and early eighteenth-century philosopher G.W. Leibniz (1646–1716). Leibniz formulated the so-called principle of reason: the principle, simply, that for everything some reason or ground can or must be rendered.

is a call to explain effects through causes, to ground, to justify, to account for something not on its own basis, but on the basis of external principles or laws.

To respond to the call of the principle of reason is to ‘render reason’, to explain effects through causes, to ground, to justify, to account for on the basis of principles or laws.

is problematic in that with the so-called ‘principle of reason’ come certain models of what it is to ‘explain’ something (i.e. by reference to some field of knowledge).

With the principle of reason come certain models of what it is to ‘explain’ something. We can understand and explain a plant, for example, by reference to the laws of biology and evolution, and ultimately perhaps in terms of the more basic laws of physics.

is the imperative that directs our epoch of techno-science.

For Heidegger, the principle names the imperative that directs our epoch of techno-science. This is not only to require of the things that encounter us that they yield up their grounds, but it is also, of course, to posit human thinking as that to which things must be brought to give reason.
