For syntactic theory, what is mean by this?

1. Traditional historical cost accounting has also been criticised on the basis of its syntactic, for example, with respect to the practice of summing several different money amounts assigned to specific assets (i.e. summing of cash held today with cash paid for land 20 years ago, which the company still holds today).
2. The internal inconsistency of historical cost accounting is similar to the philosophy of doublethink.Doublethink means the power of holding two contradicting beliefs in one's mind simultaneously, and accepting both of them.For example, valuations are incorporated in balance sheets... but the balance sheet is not a valuation statement.
