To be critical meant to raise thought so far above all constraints that, through the perception of the falseness of constraints, knowledge of the truth takes flight as if by magic.
I would like to ask whether you think that the clause "that, through the perception of the falseness of constraints, knowledge of the truth takes flight as if by magic" is a relative or object one.
To be critical meant to raise thought so far above all constraints [that, through the perception of the falseness of constraints, knowledge of the truth takes flight as if by magic].
The clause in brackets is not an object clause or a relative clause. It is a content clause licensed by the deictic degree adverb so. Because so is part of the adjective phrase so far we say that it is the indirect Complement of the adjective far. It might be easier to see how it works if we have a simpler sentence:
Clauses like this licensed by degree adverbs such as so tell us of some sort of result which explains exactly how 'X', in this case how big something is.
