This in no way results in the conclusion that the nature of scientific investigation can not be considered philosophically.
Thats apples and oranges here.
I use mutually exclusive where its necessary to use it. A Priori and A Posteriori are two completely different things. If you put them together, you've got a self contradiction on your hands.
Causes to Effects, and Effects to Causes can not coincide in the same sense at the same time. Thus, they would be considered to be mutually exclusive.
Now, a Logical Analysis of Inductive Reasoning is necessitated de facto of the Principles of Logic being both A Posteriori and A Priori.
Logic however is necessarily different than Philosophy however. So the Logic of Science is available to review, but the Philosophy of Science would be nonsense in the making.
