The easy problems of consciousness are those that seem directly susceptible to the standard methods of cognitive science, whereby a phenomenon is explained in terms of computational or neural mechanisms. The hard problems are those that seem to resist those methods.... The really hard problem of consciousness is the problem of experience. When we think and perceive, there is a whir of information-processing, but there is also a subjective aspect.... When we see, for example, we experience visual sensations: the felt quality of redness, the experience of dark and light, the quality of depth in a visual field. Other experiences go along with perception in different modalities: the sound of a clarinet, the smell of mothballs. Then there are bodily sensations, from pains to orgasms; mental images that are conjured up internally; the felt quality of emotion, and the experience of a stream of conscious thought.

The subject of a gestalt demonstration knows that his perception has shifted because he can make it shift back and forth repeatedly while he holds the same book or piece of paper in his hands. Aware that nothing in his environment has changed, he directs his attention increasingly not to the figure (duck or rabbit) but to the lines of the paper he is looking at. Ultimately he may even learn to see those lines without seeing either of the figures, and he may then say (what he could not legitimately have said earlier) that it is these lines that he really sees but that he sees them alternately as a duck and as a rabbit. ...As in all similar psychological experiments, the effectiveness of the demonstration depends upon its being analyzable in this way. Unless there were an external standard with respect to which a switch of vision could be demonstrated, no conclusion about alternate perceptual possibilities could be drawn.
Thomas Samuel Kuhn
Cordellas are invisible symbols that surface. As they do, they show the universe in a new light by the very nature of their relationships. In a very limited fashion, alphabets do the same thing, for once you have accepted certain basic verbal symbols they impose their discipline even upon your thoughts . . . and throw their particular light upon the reality you perceive. Alphabets are nevertheless tools that shape and direct perception. They are groups of relationships that you transpose upon "reality". To this extent they shape your conceptions of the world that you know. Their discipline and rigidity is considerable. Once you think of a "tree" as a tree, it takes great effort before you can see it freshly again, as a living individual entity. Cordellas do not have the same rigidity. Inner invisible relationships are allowed to rise, [with] the acknowledgment recognized reality viewed through the lenses of these emerging relationships.

Humankind does not submit passively to the power of nature. It takes control over this power. This process is not an internal or subjective one. It takes place objectively in practice, once women cease to be viewed as mere sexual beings, once we look beyond their biological functions and become conscious of their weight as an active social force. What's more, woman's consciousness of herself is not only a product of her sexuality. It reflects her position as determined by the economic structure of society, which in turn expresses the level reached by humankind in technological development and the relations between classes.
The importance of dialectical materialism lies in going beyond the inherent limits of biology, rejecting simplistic theories about our being slaves to the nature of our species, and, instead, placing facts in their social and economic context.
Thomas Sankara
Emotions are continually affecting our thought processes and decisions, below the level of our awareness. And the most common emotion of them all is the desire for pleasure and the avoidance of pain. Our thoughts almost inevitably revolve around this desire; we simply recoil from entertaining ideas that are unpleasant or painful to us. We imagine we are looking for the truth, or being realistic, when in fact we are holding on to ideas that bring a release from tension and soothe our egos, make us feel superior. This pleasure principle in thinking is the source of all of our mental biases. If you believe that you are somehow immune to any of the following biases, it is simply an example of the pleasure principle in action. Instead, it is best to search and see how they continually operate inside you, as well as learn how to identify such irrationality in others.

The division between those who try to learn about the world by manipulating it and those who can only observe it had led, in natural science, to a struggle for legitimacy. The experimentalists look down on the observers as merely telling uncheckable just-so stories, while the observers scorn the experimentalists for their cheap victories over excessively simple phenomena. In biology the two camps are now generally segregated in separate academic departments where they can go about their business unhassled by their unbelievers. But the battle is unequal because the observers' consciousness of what it is to do "real" science has been formed in a world dominated by the manipulators of nature. The observers then pretend to an exactness that they cannot achieve and they attempt to objectify a part of nature that is completely accessible only with the air of subjective tools.
