Thank you for your response. Serendipitously, I was in the process of writing about philosopher Isaiah Berlin’s philosophy that there are no simple and certain truths. All truths are contingent on a web of interconnected and overlapping elements, varied and complex, that are not reduceable to formal deductive or inductive logic.
I agree that in many cases, “I am being X” is more accurate than “I am X.” What a number of philosophies and spiritualities understand is that we have attributes that are part of our personal identities but that there remains a Self that is independent of all attributes. Most schools of Buddhist thought rejects that reality. It is not a matter of those schools confusing modal states with Self — they either reject the idea of Self or desire to negate the Self through denial of thoughts.
