What are the differences between “I am certain” and “it is certain”, and is passionate conviction ever sufficient for justifying knowledge?  Two men are standing in the street, one looks at the other and says, “If I flip this coin an equal number of times, I am certain I will always achieve identical numbers of both heads and tails.” He proceeds with flipping the coin ten times, only achieving two heads and eight tails. This man was certain he would achieve equal numbers of heads and tails, as the theoretical probability of the problem was fifty-fifty. On the other hand, it is certain that the results are random, as the coin could land on either side an infinite amount of times. Here we see one of many major differences between the phrase “I am certain” and “it is certain”.  “It is certain” relates to facts, research, scientific experiment and induction, empirical evidence, mathematics and proof. “It is certain” is usually a statement of truth and authority. It is an idea or statement that is backed up by facts, such as taking two apples and placing them in a bag with five more, and deducing the statement “It is certain two plus five is seven” as seven apples now occupy the bag. “I am certain” falls under the category of reason and logic as a way of knowing. While the phrase “it is certain” is usually accepted as a statement of truth, “I am certain” is a more personal statement and so depends more on one’s cultural background. It may be more closely linked to the category of emotion and perception as a way of knowing and, in general, be affected by human experience and therefore may differ from person to person. These two phrases, however, are commonly misused. One could say “It is certain” when one should be using “I am certain”, as the statement is not backed up by any form of reliable evidence. I once knew a child who believed the clouds moved because he pushed them with his mind. His only proof was that whenever he looked towards the sky he saw them moving, not realising they were merely being blown by gusts of wind. He developed his conclusion from empirical evidence, using his senses and inducing a theory. The child used the phrase “It is certain” when he actually meant “I am certain”, as although his own evidence supported his theory, it was in fact false. It is difficult in everyday life to determine the differences between the sayings, as they are continuously often misused. Passionate conviction, the utter belief that something is true, can be used in some situations to justify knowledge. For example, a person can believe in ghosts due to a past paranormal experience, even though there is no evidence to strongly prove the existence of such beings. They are certain they saw a ghost, and to them that is enough

to justify their knowledge that ghosts exist. It relates mainly to the statement “I am certain” and is therefore a form of emotion as a way of knowing. Passionate conviction can be used in the arts, sciences, and history as well ethics as a form of justification. The only area of knowledge where it cannot be used to any extent is mathematics.  Many people would argue that in the Arts one cannot say, “It is certain this is a wonderful piece of art” as everyone’s perception is different and that passionate conviction can be used to justify a person’s feelings ...
