There is no way we can talk about intolerance without first understanding the roles of prejudices. It is the major factor that breeds intolerance among people. Prejudices are formed in our mind and independently about each and everything we know. It comes in varying forms and degrees infiltrating gradually into various things we know and do.
Prejudice can be good sometimes when we use it as an avenue to understand more about a situation. Many would argue that when prejudice is helping us to understand a situation, it means that our final opinion about that situation has not been formed and therefore it isn’t qualified enough to be called prejudice, but I prefer to assert that prejudice that we formed to help us to understand something better is still at the level of skepticism. Skepticism sometimes might have unalienable elements of prejudice. “Skepticism is generally any questioning attitude towards unempirical knowledge or opinions/beliefs stated as facts, or doubt regarding claims that are taken for granted elsewhere.”
Doubt is a product of skepticism, and skepticism can lead to prejudice if we couldn’t find a better way to understand the matter better than it is revealed. Prejudice can also lead people into doubt, and therefore the three – doubt, skepticism and prejudice seem to be interwoven and sometimes could be confusing.
Sometimes, when we doubt, it is out of our prejudices. Skepticism is not totally doubt, but rather could be said to be a kind of unconfirmed doubt in our minds. When we are skeptical, it means that we are at a point unable to make valid strong and unshakable decisions about issues we are giving our views about. Doubt simply means we have taken decision about a thing or a situation and therefore have given our verdict which is in negation to the situation at hand. When we doubt, it means that we are opposing the proposition that has been given to us. It means that we can’t affirm the veracity of such proposition and thus give it our doubt.
Prejudice is neither doubt nor skepticism. But then, all doubts and skepticisms we have in our minds are nothing but products of prejudgment we already have in our minds. This prejudgment is exactly what we meant by prejudice. Prejudice therefore can influence our decisions, and our decision about a situation might either be that we should doubt it or that we should sit on the fence (being skeptical) about it.
The prejudice in someone’s mind is the foundation of his intolerance. When prejudice means inability to give proper analysis of a situation before passing a judgment, then it involves that certain judgement has already been formed in our minds about the situation. No judgement passed out of prejudice should be allowed to be valid. When in law court, a judge is openly (through his utterances and/or body languages) seems to be favouring a particular side in a case in his court, then verdict from such judgement needs urgent appeal. Thus, to be a good judge, someone needs to remove every garment of prejudice and enrobe himself with that of impartial and unbiased decision which must have risen from evidences and testimonies available.
