What are the differences between “I am certain” and “it is certain”, and is passionate conviction ever sufficient for justifying knowledge.

The main aim of this essay is to discuss the differences between the more personalized phrase, “I am certain” with the more generalized term, “it is certain”.  After this I will discuss whether the passionate conviction of an individual is enough to justify knowledge without the use of logical reasoning.  However, passionate conviction even though it may be perceived by one person, it may not be proven false. Empiricism can be defined as ‘the practice of medicine that disregards scientific theory and relies solely on practical experience’. In contrast, rationalism is defined as ‘reliance on reason as the best guide for belief and action’. Knowledge is defined as the ‘psychological result of perception and learning and reasoning’.

In the above context, we first need to define what we mean by “certain”.  The first ‘certain’ means I am convinced.  The second ‘certain’ means it is indisputable.  “Certainty is the acceptance of fact without doubt. When should one be certain? When all knowledge supports the conclusion, and no one denies it.  If one has a valid reason for doubting something, one should not be certain. Certainty is contextual.  It is based on one’s current knowledge.  It is possible to be certain, and still be wrong.  They can form conclusions, but there is the possibility of error.  Humans need knowledge, though, and need a basis for accepting knowledge as true.  They cannot live constantly doubting every piece of knowledge.  To survive, they must be able to accept knowledge as true, and act accordingly.”

After giving a bit of background information about what certainty is a whole, now I feel I can discuss limitations of the word “I am certain”.  “Only when we know little can we be certain; doubt grows with greater learning.”  This quote from the German philosopher, Goethe demonstrates that with the use of the “I am certain”, you are restricting yourself to only the knowledge that you have acquired. Today I am certain it is going to rain.  I am making this judgement because of all of the dark clouds in the sky and this information was passed down to ...
