In his book Physics of the Impossible, Michio Kaku thinks that psycho-kinesis-i.e., a direct causal influence on physical processes by mental powers-will become a real possibility in a near future. From the point of view of metaphysical realism, this means that mental entities and mental causality are real phenomena. Contemporary scientific methodology regards the use of scientific instruments that amplify our sensibilities as a cognitive technology that deepens our knowledge of, and power over, real processes. It appears that the strongest and most productive methods are connected with scientific theories-they are theories ''in action''. Thus, scientific theories can regarded as mental cognitive technology by means of which humans get to know, and at the same time shape, reality. and Břetislav Fajkus
