 No matter how desirable, our ability to use scientific claims to represent facts about the world depends on whether these claims can unambiguously be established on the basis of evidence, and of evidence alone. Alas, the relation between evidence and scientific hypothesis is not straightforward.  Subsection 2.2  and  subsection 2.3  will look at two challenges of the idea that even the best scientific method will yield claims that describe an aperspectival view from nowhere.  Section 5.2  will deal with socially motivated criticisms of the view from nowhere.
