The acquisition of knowledge is not a single unrelated occasion but rather an adaptive process in which past acquisitions modify present and future ones. In Part I of this essay in epistemology it is argued that coping with knowledge is not a passive affair but dynamic and active, involving its continuance into the stages of assimilation and deployment. In Part II a number of specific issues are raised and discussed in order to explore the dimensions and the depths of the workings of adaptive knowing.
