Denkpsychologie has been important for the development of psychology as well as of philosophy during the last century. More specifically, cognitive psychology as well as Karl Popper’s evolutionary epistemology were both influenced by Otto Selz’s cognitive psychology. Without doubt, Selz played a role in the development of Popper’s thinking, but Michel ter Hark has not given convincing evidence for Popper’s idea of bold conjectures being influenced by Selz.

In recent years Sir Karl Popper has been turning his attention more and more towards philosophical problems arising from biology, particularly evolutionary biology. Popper suggests that perhaps neo-Darwinian evolutionary theory is better categorized as a metaphysical research program than as a scientific theory. In this paper it is argued that Popper can draw his conclusions only because he is abysmally ignorant of the current status of biological thought and that Popper's criticisms of biology are without force and his suggestions for its improvement are without need. Also it is suggested that Popper's desire to see scientific theory growth as being in some sense evolutionary may have led him astray about biology. And conversely it is suggested that since his claims about biology are not well taken his analysis of theory growth may well bear reexamination.

First, a brief history is provided of Popper's views on the status of evolutionary biology as a science. The views of some prominent biologists are then canvassed on the matter of falsifiability and its relation to evolutionary biology. Following that, I argue that Popper's programme of falsifiability does indeed exclude evolutionary biology from within the circumference of genuine science, that Popper's programme is fundamentally incoherent, and that the correction of this incoherence results in a greatly expanded and much more realistic concept of what is empirical, resulting in the inclusion of evolutionary biology. Finally, this expanded concept of empirical is applied to two particular problems in evolutionary biology — viz., the species problem and the debate over the theory of punctuated equilibria — and it is argued that both of them are still mainly metaphysical.

This paper expounds the central tenets of the Austro-German school of evolutionary epistemology and points out that it conflicts in important aspects with Popper's. The conflict arises because some of the members of the above-mentioned school consider induction to be an absolutely central feature of any evolutionary epistemology. Thus the question arises if Poppers 'method of trial-and-error' is still to be considered to be the evolutionary method. The present author suggests that what is being selected for during scientific evolution is our capacity to apply induction appropriately. We learn when to use induction reliably and when to resort to the most elementary of all methods, the method of trial-and-error.

Abstract Evolutionary epistemologists from Popper to Campbell have appropriated the Darwinian principle to explain the apparent fit between the world and our knowledge of it. I argue that this strategy suffers from the lack of any principled distinction among various types of elimination. I offer such a distinction and show that there is a species of elimination that is really corrective, that is, which violates the Darwinian principle as Popper understands it.

Donald T. Campbell outlines an epistemological theory that attempts to be faithful to evolution through natural selection. He takes his position to be consistent with that of Karl R. Popper, whom he credits as the primary advocate of his day for natural selection epistemology. Campbell writes that neither he nor Popper want to give up the goal of objectivity or objective truth, in spite of their evolutionary epistemology. In discussing the conflict between an epistemology based on natural selection and objective truth, Campbell cites an article by the German sociologist and philosopher Georg Simmel entitled 'On a Connection of Selection Theory to Epistemology', as presenting the issue in a notably forthright manner.The present essay summarizes Simmel's article, with the purpose of clarifying, in terms that Campbell apparently finds satisfactory, the conflict that Campbell acknowledges between an evolutionary epistemology and ultimate truth; the essay then examines the responses of Campbell and Popper to Simmel's position. While Campbell and Popper acknowledge the work of Simmel, their responses suggest something less than a full consideration of Simmel's position.

Karl Popper has been one of the few philosophers of sciences who has influenced scientists. I evaluate Popper's influence on our understanding of evolutionary theory from his earliest publications to the present. Popper concluded that three sorts of statements in evolutionary biology are not genuine laws of nature. I take him to be right on this score. Popper's later distinction between evolutionary theory as a metaphysical research program and as a scientific theory led more than one scientist to misunderstand his position on evolutionary theory as a scientific theory. In his later work Popper also introduced what he took to be improvements of evolutionary theory. Thus far these improvements have had almost no influence on evolutionary biology. I conclude by examining the influence of Popper on the reception of cladistic analysis.
