Is it possible, simply through the study of psychology and without knowledge of mathematics, to tell that 2+2=5 is wrong? Simply through the survey of the internal contents of the mind, can you make any judgement about what is true or false? You cannot tell whether affirming the consequent and denying the antecedent are fallacious forms of reasoning or not. For that, psychology has to turn to other sciences, and so it must necessarily presuppose others. Or take Transcendental Phenomenology, which is the study of phenomena - the subject matter of this science. To arrive at this phenomena we have to abstract from real existence and concentrate on how things appear to consciousness. This epoche, as Husserl calls it, drives a wedge between meaning and reality, but this separation is presupposed within the science and not justified within it. The phenomenological reduction is, as a consequence selective; it knows what it negates and what it preserves. There is already a duality of meaning a...
Reality cannot be only what our brain perceives because the finitude of all our claims demonstrates the opposite. Is ‘true for me’ true? If it were, it would not conflict with another truth claim. If it is said there is no conflict because ‘true for me’ is true, then there is conflict. If I say ‘this is sweet’ is true for me, and ‘this is sour’ is true for another, and there is no conflict between the two claims, it should be asked whether true for me means the same as true or not. If it doesn’t, then that implies true-for-me and truth are not identical; if it does, then there are two contradictory truth claims, and that means ‘true-for-me’ and truth are not identical. What is real is also objective - applicable across subjective perspectives. If I run into a thief who believes it is right to murder me for money, and if I think I should not die, but if I also believe that he is right from his perspective to think so, then I am going to die. Can I, however, think that I am right t...
