Certainty and Uncertainty
Keywords:praxiologia, incerteza, previsão
AbstractThe present text exposes the Misesian conception on the differences between the methods of the natural sciences and the sciences of human action, or praxiology. It rejects the empiricism applied to the latter insofar as the complexity of human phenomena results in the inexistence of constants from which empirical laws and exact predictions could be obtained. It criticizes the demand for accurate predictions that disregard the impossibility of eradicating the uncertainty inherent in the sphere of action. The text then rejects the relevance of the Popperian demarcation criterion applied to praxiology, reaffirming that the laws of a praxiological nature are aprioristic, derived deductively from the recognition of the nature of the human mind.
