dhw: Thank you for confirming the process I keep trying to describe. Shapiro tells us that bacteria are sentient, cognitive, intelligent beings. That means they deliberately rewrite their DNA to develop new ways of reaction.

David: I am with Shapiro until he introduces the word 'cognitive' which implies thought. 'Sentient' is correct. Bacteria receive stimuli and recognize them and respond.

dhw: It is the ability to rewrite DNA to develop new ways of reaction/new organs that constitutes the inventive mechanism, and according to Shapiro that ability is conscious.

David: Understood, not accepted as conscious.

I accept his word cognitive as cognition, the ability to receive knowledge and learn it so as to act on it, which action I will only accept as automatic molecular reactions. The only inventive ability of cells is their mechanism to modify DNA and therefore the action if their genes. You and I agree on this last point.
