In his paper the author establishes some arguments against the thesis of professor Walter Schweidler. The later defends the anti-representationalist claim that not every kind of knowledge is to evaluate on its truth and falsehood. The author maintains the opposite thesis that the all knowledge including the one about social premises of any kind of science may be evaluated (although not eventually proved) on their truth or falseness.
