Scientists (and philosophers) have a tendency to be led by their activity and language into seeking explanations for things, but the explanations (like the questions) are empty, or anyway are not what we really want. Scientists and philosophers are correct in attempting to describe how things happen, but when they are led by their misapprehension of language into attempting to explain why things happen, then they find themselves involved with projects in which they really don't know what they are doing.
I would not be surprised
if the activity of pursuing "unified" theories is similarly credulous;
and it is also unprofitable (that is, it does nothing to advance
science, philosophical understanding, well-being, or wealth).
I suspect that an investigation will show that the quest to answer how leads to liberalizing epistemological and political habits, while
seeking answers to why leads to authoritarianism.
