"A theory aspires to some degree of generality and abstraction." The book where I found this sentence is a book in one of the disciplines of humanities. According to Merriam-Webster, "abstraction" means:
1a: the act or process of abstracting : the state of being abstracted
1b: an abstract idea or term
2: absence of mind or preoccupation
3: abstract quality or character
4a: an abstract composition or creation in art
4b: ABSTRACTIONISM
I have absolutely no idea what to make of "abstraction" here. Please help me select the correct meaning from the above list so that I can correctly understand what the author is trying to say. Thank you in advance. :)
