Theory of knowledge


Theory of Knowledge or Epistemology is concerned with credibility or certainty in various types of propositions.

The area also discusses how we reason, what denotes credible arguments and about how we may evaluate credibility.

The main questions circle around if certainty exists at all.

Form sense impressions, that are not absolutely trustworth, the only source of credibility, or exists in addition credibility that is "absolutely certain", or "absolutely true"?


Our brain is incredible capable. It can remember, find what it has remembered, and it can reason. In addition it checks many bodily functions on its own.

I discuss how the brain performs reasoning and tries to show how rather simple processes may lead to complicated results like phantasy and knowledge.

Some of these discussions are, as far as I know new:

- An attempt to estimate the speed of the brain.

- How the brain remembers concepts.

- A reformed view of analysis that leads to that reasoning actually works.

- How the brain perform reasoning only by using synthesis and analysis.






Our brain performs an incredible amount of reasoning in every moment.

Philosophers that have not understood the speed of the brain have searched for complicated explanations for the brain's simple but efficient basal activities.

A faded pot plant provides a simplified example of how we form knowledge.

During later years it has been possible to acquire fascinating images that weakly indicate the brain's complexity.



Different forms of knowledge are created through reasoning that ultimately is based on perception.

An additional form of knowledge is formed by previous generation's ability to reproduce.

Reasoning may be reduced into two basic processes that are performed simultaneously in the brain: Synthesis and analysis. During synthesis the brain forms connections between related phenomena and during analysis the brain finds and follows these connections.

The credibility of the conclusion in a logically correct argument is determined by the credibility of the premises.

The human brain's "default mode network" [Horn], i.e. neural connections between different centres of the brain (yellow in the image below). See also wikipedia. According to the discussions at this website, syntheses and analyses are performed at these centres. (Larger image)
