  McCrea’s overall view is that theories are set up to be hypothetico-deductive in structure. His account is based on his view of the evolution of theories of space-time and mechanics, beginning with Newton, through the General Theory of Relativity and ending in kinematic relativity. His argument reduces to the claim that, insofar as Milne and e.g., Newton, can be shown to follow the same procedure, any attack upon Milne is also an attack upon Newton. First, he states his goals in the paper.
