 An important and still largely unexplored claim of Husserl’s is that any logically consistent meaning can in principle be subjectively fulfilled, more or less adequately, by a unified intuition, such as an act of continuous perception or intuitive imagination, where the structure and other essential features of the meaning in question can be read off from the respective mode of intuitive fulfillment. Inconsistent meanings can be singled out and studied by means of (reflection upon) corresponding experiences of intuitive conflict, like for instance the discrete switching back and forth between a duck-head-imagination and a rabbit-head-imagination in the case of an attempted intuitive imagination of a duck-head that is at the same time a rabbit-head. Some meanings are inconsistent for formal-logical reasons. According to Husserl, all analytically false propositions belong to this category. Other meanings are inconsistent because they conflict with some general material a priori truth, also called “essential law”. The proposition expressed by the sentence “There are perceptual objects whose surface is both (visibly) completely green and completely red at the same time” is a case in point.
