 Twardowski's mature theory of meaning is connected with the rigorous definition of the distinction between actions and products of actions (while in Relative Truths he speaks of judgments as actions or products). On the basis of grammatical analyses, purporting however to show logically salient differences, Twardowski establishes a basic distinction between physical, psychical (i.e. mental), and psychophysical actions and their products. The analysis is reminiscent in philosophical style of that of ‘the presented’ in Content and Object, though more general, and a nice example of the method which has become now strongly associated with analytic philosophy.
