” (Bernard, 1878, cited by Cannon, 1929). Cannon translated Bernard’s observation to the product of homeostasis, which assumes physiological processes to keep up a steady condition via feedback (Cannon 1929). An earlier publication (Peper 2004a) demonstrates which the design of homeostasis will not be satisfactory to describe the effect of repeated disturbances on the performing of residing organisms and argues that, as opposed to retaining a gentle point out as Cannon proposed, dwelling organisms are frequently striving for the best obtainable compromise of their performing in continuously transforming instances.
