"Intentionality is aboutness. Some things are about other things: a belief can be about icebergs, but an iceberg is not about anything; an idea can be about the number 7, but the number 7 is not about anything; a book or a film can be about Paris, but Paris is not about anything. Philosophers have long been concerned with the analysis of the phenomenon of intentionality, which has seemed to many to be a fundamental feature of mental states and events."
"If HAL believed (we can't be sure on what grounds) that his being so rendered comatose would jeopardize the whole mission, then he would be in exactly the same moral dilemma a human being in the same predicament would face. Not surprisingly, we figure out the answer to our question by figuring out what would be true if we put ourselves in Hal's place. If you believed the mission to which your life was devoted was more important, in the last analysis, than anything else, what would you do?"
"Are original intentionality and intrinsic intentionality the same thing? We will have to approach this question indirectly, by pursuing various attempts to draw a sharp distinction between the way our minds (or mental states) have meaning, and the way other things do."
