      2. Leibniz

        1. "17. Moreover, it must be confessed that perception and that which depends upon it are inexplicable on mechanical grounds, that is to say, by means of figures and motions. And supposing there were a machine, so constructed as to think, feel, and have perception, it might be conceived as increased in size, while keeping the same proportions, so that one might go into it as into a mill. That being so, we should, on examining its interior, find only parts which work one upon another, and never anything by which to explain a perception. Thus it is in a simple substance, and not in a compound or in a machine, that perception must be sought for. Further, nothing but this (namely, perceptions and their changes) can be found in a simple substance. It is also in this alone that all the internal activities of simple substances can consist." —From The Monadology (trans. Robert Latta)

        • "Whenever an organism at a given moment of stimulation shifts from being ready to respond in some relatively less differentiated way to being ready to respond in some relatively more differentiated way, there is consciousness."

            • This is so good, I can't help but quote it here (Dennett 2005 also cites it):

                "I would like to speak briefly about some of the advantages of the pandemonium model as an actual model of conscious behaviour. In observing a brain, one should make a distinction between that aspect of the behaviour which is available consciously, and those behaviours, no doubt equally important, but which proceed unconsciously. If one conceives of the brain as a pandemonium—a collection of demons—perhaps what is going on within the demons can be regarded as the unconscious part of thought, and what the demons are publicly shouting for each other to hear, as the conscious part of thought."

        • Crick's "Astonishing Hypothesis":

          "...‘You’, your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are i fact no more than the behavior of a vast assembly of nerve cells and their associated molecules."

            • "He acknowledges that in the end science cannot actually say what it's like to be a bird. His subtitle was drawn from the philosopher Thomas Nagel, who wrote an essay about consciousness called ‘What Is It Like to Be a Bat?’ The scientist has no more luck than the philosopher in answering the fundamental question, and for the same reason. We have no way to know the subjective experience of bat or bird, nor neighbor or spouse, no matter how much information we have on how their senses work or on the structure of their brains. The only subjective experience we have is our own. But the attempt to get at what a bird sees, hears, feels and thinks is more than worth the effort because there are so many intriguing facts and stories that the reader learns along the way."

            "Q. When referring to a zombie, should I use the relative pronoun who (which would refer to a person) or that (since, technically, the zombie is no longer living)? Essentially, does a zombie cease to become a ‘person’ in the grammatical sense?

            "A. Let's assume this is a serious question, in which case you, as the writer, get to decide just how much humanity (if any) and grammatical sense you wish to invest in said zombie. That will guide your choice of who or that."

          • A good, general discussion of (un)consciousness.
          • On philosophical zombies and phenomenal-vs.-"psychological" consciousness:

            • "One thing is now clear: consciousness is not to be identified with any particular perceptual-cognitive functions such as discriminative response to stimulation, perception, memory, or the higher mental processes involved in judgment or problem-solving. All of these functions can take place outside of phenomenal awareness. Rather, consciousness is an experiential quality that may accompany any of these functions. The fact of conscious awareness may have particular consequences for psychological function—it seems necessary for voluntary control, for example, as well as for communicating one's mental states to others. But it is not necessary for complex psychological fimctioning." (p. 1450, col. 2.)

        • Wonderful title, computationally sympathetic, but ultimately disappointing. Has a terrific chapter (Ch. 8) on the "hard" problem of qualia, which is well worth reading and pinpoints exactly why the problem is hard. But his solution, though offered as a counterpoint to Dennett's view, is ultimately not much better than Dennett's, though offering more detail. One problem is that he analyzes qualia in terms of interaction, but how would he explain mental imagery or memories of qualia, which don't involve interaction? And one of his principal claims…

            If we take experiencing a raw feel to be an activity of interacting with the world, then by this very definition, there must be something it's like for this interaction to be happening: Interactions always have some quality or other. (Ch. 14, p. 165.)

          …simply begs the question. (After all, what is it that explains why and how the interactions have quality?)
