The consequences of the uncertainty principle are vast. For one, it limits the notion of  causality. The hope of physics previously had been that if all forces were understood,  then the exact position and velocity of a particle could be determined for any given  moment in the future. However, such determinism was impossible if the exact  measurement of original position and velocity could not be accomplished. Indeed, the  best that one could attain would be the range of possibilities at any future time;  therefore, the laws of quantum mechanics were really statistical rather than exact. In  later philosophical works and lectures, Heisenberg would challenge the principles of  Kant, whose epistemology depended on the validity of causality. Heisenberg did not, of  course, attempt to propose solutions, but rather directed people in other professions in  their search and the factors to consider. Published in 1927, Heisenberg's uncertainty paper, entitled "On the Perceptual Content
