Mental Actions as a Basis for the Formation of Thoughts and Images

Abstract The ability to perform an action mentally makes possible foreseeing the results of that action if and when it becomes external. This is so important that no one can deny the significance of the question of the formation of mental actions, i.e., under what conditions they are formed correctly, what causes possible aberrations in them, and by what means these aberrations can be eliminated. But the opinion is still often encountered that the significance of this question is nonetheless still limited to two areas: first, to the sphere of exclusively mental, intellectual processes and, second, to the interests of pedagogy and, even more restrictively, to the method by which these mental actions are taught.
