These sayings suggest that everything is just a matter of personal opinion. They suggest that there is no objective reality and that we all just exist in our own separate subjective realities of our own making, and that each opinion on reality has as much validity, credibility, weight and veracity as the next opinion.
Firstly, whether or not each of us have a personal view of the world, does not make each personal view reasonable. So how do we measure, assess, and evaluate information?
Human beings do not individually think the same, process information in the same manner or come to the same conclusions. We don't think the same way because we are all individually products of not only our environments, cultures, education etc, but we are also individuals according to our genetic prescriptors.
Having stated that we are all individuals with individual potentials, how do we assess or test information for veracity? One way to do this, and the most successful way of examining or critically analysing information so far, is through the use of reason. So, how each of us come to conclusions and the steps we use to arrive at those conclusions can be examined and tested according to reason and the laws of logic.
In the case of argument, reason is the ability of the human mind to form and operate on concepts in abstraction. Reason is used in accordance with rationality and logic in order to come to a decision about propositions, ideas, concepts, or beliefs.
Reason is the process of thinking which allows one to differentiate between a logical argument and a flawed argument. For example: If it can be shown that there is a flaw in one of the thought steps, then the conclusion is also likely to be flawed.
If, an individial lives in a world where they believe that everything is possible, it could be argued that they are essentially dooming themselves to a life of stasis, paralysis, and intellectual immobility.
Without the use of reason, everything we can imagine becomes a possibility as there is then no method to test for what is reasonable.
Therefore, if you claim to believe that everything is possible, what is to stop you from believing that if you think of a terrible human-eating monster that it will appear? And if you believed that it is possible for a monster to materialise simply through wishing it, you would try to not think, just in case your thoughts miraculously created said monster on top of your computer monitor.
Many things that humans can imagine, are considered to be highly improbable and are summarily dismissed through the use of reason.
What is also interesting is the notion that the above sayings only offer two choices. The choices of loss or gain, spam or art, treasure or trash, thorn or thistle. This type of thinking encourages people to think in black or white, either this or that, and is an example of the false dichotomy or the false dilema.
Flawed thinking often results in flawed conclusions. Just as flawed beliefs can result in human hood ornaments.
