Document Summary
Journals resume the week after the week after break. 1s--to have the thought in the way we have such thought we need to interpret these symbols: we could use a and b to use the symbols 1 and 0: a =1, b = 0. Interpretation: assigning a symbol to the 0s and 1s. In humans: interpretations of words and sentences: nobody knows how the language of thought comes to have meaning/interpretations, operation: number of distinct moves you can make in a turing machine (writing, erasing. Symbols aren"t enough to be thoughts because there has to be meaning to the thought: there is no meaning to "green ideas sleep furiously"; there is no semantics, meaning of language is a mystery, an unsolved problem. Like the 0s and 1s, the lot is a physical symbol system. Feb. 26: there are physical entities that are governed by a syntax, these entities are then interpreted to have meanings and to be true or false.
