Thought, in a general sense, is commonly conceived as something arising from the stimulation of neurons in the brain. Current understanding of neurons and the central nervous system implies that the process of learning corresponds to changes in the relationship between certain neurons in the brain. Research is ongoing in this area.
It is generally recognized that memory is more easily retained when multiple parts of the brain are stimulated, such as through combinations of hearing, seeing, smelling, motor skills, touch sense, and logical thinking.
Repeating thoughts and actions is an essential part of learning. Thinking about a specific memory will make it easy to recall. This is the reason why reviews are such an integral part of education. On first performing a task, it is difficult as there is no path from axon to dendrite. After several repetitions a pathway begins to form and the task becomes easier. When the task becomes so easy that you can perform it at any time, the pathway is fully formed. The speed at which a pathway is formed depends on the individual, but is usually localized resulting in talents.
Philosophers have forever been concerned with political and social matters. Not only have they asked how politics work but mainly, how they should work. These philosophers have been concerned with the nature and justification of political obligation and authority and the goals of political action. Although their doctrines have differentiated, and numerous have been utopian in concept, they have all shared the same ideas and convictions that it is the political philosopher?s duty to distinguish between what is and what ought to be, between existing political institutions and potentially more humane institutions. Throughout the centuries, philosophers have debated over the moral issues involved in the search for the ideal society. Three influential philosophers in this field have been Plato, John Locke and Karl Marx. Their philosophies and utopian states have continually influenced political actions and thoughts throughout the ages.
The idea of unmarked categories originated in feminism. The theory analyzes the culture of the powerful. The powerful comprise those people in society with easy access to resources, those who can exercise power without considering their actions. For the powerful, their culture seems obvious; for the powerless, on the other hand, it remains out of reach, élite and expensive.
The unmarked category can form the identifying mark of the powerful. The unmarked category becomes the standard against which to measure everything else. For most Western readers, it is posited that if a protagonist?s race is not indicated, it will be assumed by the reader that the protagonist is Caucasian; if a sexual identity is not indicated, it will be assumed by the reader that the protagonist is heterosexual; if the gender of a body is not indicated, it will be assumed by the reader that it is male; if a disability is not indicated, it will be assumed by the reader that the protagonist is able bodied, just as a set of examples.
One can often overlook unmarked categories. Whiteness forms an unmarked category not commonly visible to the powerful, as they often fall within this category. The unmarked category becomes the norm, with the other categories relegated to deviant status. Social groups can apply this view of power to race, gender, and disability without modification: the able body is the neutral body; the man is the normal status.
