Knowledge

Epistemology is the philosophical study of knowledge, and although I will not wax philosophical here today, it is interesting to read what Wikipedia has to say on this subject. One important aspect of knowledge is "how do we know what we think we know?".

As simple as knowledge might seem, it's not simple. There are numerous ways of obtaining knowledge, some of which are more reliable than others while some sources are outright propaganda intended to deceive with false information. And there can be false knowledge, even self deception. People also tend to become invested in what they think they know to the point where contradictory information is routinely disregarded because they already "know" the truth. Mass delusions are common in human history and these delusions are the foundation of despotic rulers, empires, cults and a host of evils throughout history; all perpetrated by people with knowledge of the truth and accepted by the masses who believed the lie.

Give some thought to what you "know" and be willing to debate it, to listen to contradictory evidence, and if you can't defend what you "know", find out how to do so or change your mind and accept the truth no matter how heavily invested you are in the alternative.
