Truth requires extrospection and perception through our senses. To hold solipsism and idealism as a real possibility is to deny the very things you need to affirm idealism and solipsism. A blind man cannot form the concept of colour, someone who promotes idealism cuts off their own head, in order to state "look I have no head".
What demonstrable truths have been uncovered through any method, which do not require the acceptance of assumptions which would beg the question? I can't think of any. . . can you?
