In this paper we will investigate exactly that: we will conjecture on the origin of basic instruments of logical thinking. As the starting point we consider a very general case of a subject interacting with an environment. The subject might often have a choice of actions to take. Additionally, it is of fundamental importance that as a rule the subject's internal representations of (beliefs about) the environment are inaccurate. Beginning with this very general schema we will eventually arrive at a possible mechanism of how Logic could have emerged. Our reasoning will be supported with some in-depth case studies.8 pages, 0 figuresGeneral MathematicsLogic03B30 (primary), 03B05 (secondary)text
