Evolution and Rationality

Kant's dedication in the B edition of the Critique of Pure Reason to Bacon seems to correspond to a substantive revision--Cognition as a constructive process, as signified in the text by the repeated example of the drawing of a line. Nevertheless, his appreciation of Bacon seems to fall short of the full implication of the pioneering method of the latter--that Pure Reason is fundamentally Experimental. On that basis, the Necessity of Reason does not preclude lacunae, either Diachronic or Synchronic.  For, if Reason is Experimental, then the possibilities of failure and incoherence are inherent.  Accordingly, Evolution can be Rational without being Mechanical, and an Ecosystem can be Rational and still entail internal conflict.  Thus, neither regressive or stagnant phases of Human history, nor environmentally destructive Human industrial processes, refute the concept of Evolution--including its Ecological dimension, as has been previously discussed--as Rational.
