'Complete certainty,' what exactly does that mean? It seems to imply that we are able to know something without doubtfulness. In fact, it seems to be saying that it is a justified true belief. But what makes a 'complete certainty' 'complete' and 'certain.' To understand this we must first understand and grasp what the two areas of knowledge of mathematics and the natural sciences say they accomplish this goal. We must first understand what makes something a complete certainty to the scientists and mathematicians that study in these subjects and how the people, who believe in their findings, accept these 'complete certainties.'
Mathematics and the natural sciences are both hard sciences that are consistently backed up by evidence and proof. Because of this, these two areas of knowledge are usually picked as the best in terms of gaining absolute certainty. Both are supported and backed by numbers and this makes the two more precise, which makes it a lot more accepted and understandable than ethics and religions. Numbers give the ability of universal language between people and allows everyone to understand each other without the barriers of misconceptions. In pertaining to the four ways of knowing, let us see how mathematics achieves 'complete certainty' and the extent to which it falters.
Mathematicians believe that since math is a very concrete and hard science, it is pretty much infallible. Through reason, math can consistently prove itself with numbers and evidence of working algorithms and equations that will always have the same answers as long as the laws of math are followed. Though, some math concepts are theoretical, most are laws that cannot be disproven. For example, the laws of addition, subtraction, multiplicat...

...e this hard science of nutrition, one of uncertainty, and not 'complete certainty.'
Unclearnesses in natural sciences like this and even in math affects certainty in many sciences. Many scientists use math that can be accurate but uncertain, and this can further prevent them from reaching 'complete certainty.' Relations between areas of knowledge in broad make it hard to state whether 'complete certainty' is even remotely possible in natural sciences and in mathematics. “As the physicist Richard Feynman once said: 'Science is a long history of learning how not to fool ourselves.'” It is this very quote into why the natural sciences and mathematics have had a great success into finding 'complete certainties.' That limit on their extent however, can only become less and less as we advance in technologies and realize where we can improve on our errors and fallacies.
It might seem that we really know a lot about this planet we live on. But how much do we really ‘know’ the things of this world? Could it be that the things we thought we knew with certainty is really not as absolute as we thought it is? In Rene Descartes’ “Meditation on the First Philosophy,” he says as follows about fundamental knowledge: “Certainly, up to now whatever I have accepted as fully true I have learned either from or by means of the senses: but I have discovered that they sometimes deceive us, and prudence dictates that we should never fully trust those who have deceived us even once. But perhaps, although they sometimes deceive us about things that are little, ...
Barry begins his account with contrasting the strength of certainty and the weakness of uncertainty to better define the term uncertainty. This sophisticated antithesis initiates a contrast between the
Does certainty actually provide security, or does it set one for failure? Does doubt cause negativity or does it prepare one for the future? The idea whether certainty or doubt causes the fulfillment of dreams, goals and the future as questioned many. Certainty creates security and assurances, but is anything certain? Nothing in the world is ever certain; one’s world can be flipped upside down in the matters of days, hours, minutes and even a split of a second. Unlike certainty, doubt allows one to know there is a chance that the odds are against one. William Lyon Phelps supports certainty as a factor for success, while Bertrand Russell favors doubt because it creates comfort and prepares one for reality. Using personal knowledge and historical evidence, Bertrand Russell’s idea that doubt creates possibilities and hard work is valid, while William Lyon Phelps claims the opposite, that certainty creates success.
In the second meditation of Descartes, he continues his topic about doubt and certainty. And he doubts that nothing is certain and wanted to use the Archimedes’s methods – “Demand just one firm and immovable point in order to shift the entire earth.” (Descartes, p394) - to make something certain. And the starting point is to find at least one thing that he can assure is “certain and unshakeable” (Descartes, p354).
Descartes was the first western philosopher to attempt to educate others on a puzzling question: how can one know with certainty anything about the world around us? “I realized that it was necessary, once in the course of my life, to demolish everything completely and start again right from the foundations if I wanted to establish anything at all in the sciences that was stable and likely to last” (Med 1, 12). In writing this meditation Descartes freed his mind of all information, and encourages the reader to do so as well, so that he could destroy established opinions. In order to determine whether there is anything we can know with certainty, he concludes that we must disregard all we were taught and then rebuild our knowledge into new and exciting philosophical foundations. If there was any notion that cannot be questioned, we should, for the time being, pretend that everything we know is disputable. However, Descartes did find the possibility of fully doubting absolutely everything unachievable, as one cannot truthfully fake all studied knowledge. However, he suggested that we, as skeptics, should doubt individual principles and think for ourselves.
I am perfectly willing to grant Unger the first premise. I think that there is no problem with allowing him this, in and of itself. Even the second premise is allowable in a certain, philosophically interesting sense, and in this sense, Unger’s argument is very strong. The philosophical ideal of absolute certainty is something that I think should be given up as a vain pursuit, and I think that Unger shows this nicely.
...ntific it is possible that it may be proven wrong when the theory is actually correct, just that the experiment chosen to test the theory is wrong. As I have already mentioned, I feel that too look at the theory in terms of science is damaging to a theory which doesn't need scientific backing to justify it. I feel that it is just as important to discover truths by observation and deduction as it is to do so in a strictly scientific manner.

Nothing in life is certain. One can never truly be sure of anything. In fact life is a constant struggle between doubt and certainty. We are constantly reminded that certainty in a future profession or dream will lead to success but this is simply not true. When we look at everything that is believed to be true, how do we know that it is true with absolute certainty? Certainty in and of itself is unobtainable. As humans beings we have doubts about everything no matter how desperately we want to believe it is true.
Fundamentally, mathematics is an area of knowledge that provides the necessary order that is needed to explain the chaotic nature of the world. There is a controversy as to whether math is invented or discovered. The truth is that mathematics is both invented and discovered; mathematics enable mathematicians to formulate the intangible and even the abstract. For example, time and the number zero are inventions that allow us to believe that there is order to the chaos that surrounds us. In reality, t...
The relationship between certainty and doubt has been a heavily debated topic throughout history and especially in the mid-1800s. For most people, having some doubt on one’s opinions is much more beneficial than having absolute certainty because doubt allows one to review his potential choice and leaves room for him to make improvements on his choice. Someone who lives with absolute certainty cannot weigh the pros and cons because he has the confidence that what he believes is the right decision for everyone; however, there are situations in one’s life where absolute certainty is necessary, such as in team sports. With the exception of competitions, however, it is more important for one to have doubt in his or her life because doubt allows
...our questions, we need to work hard to acquire training in learning scientific materials either through a teacher or with our own strive in gaining knowledge. Our modern world is based on science’s role and different aspects of scientific effort to clarify and to shed light to our problematic conditions. More over, as human being, we all want to have a pleasurable enlighten for our doubts or curiosity, nevertheless, we need to realize that, there is limitation to all of these discoveries. We need to consider that scientist always do their best for welfare of human conditions. yet we can’t hid the fact that the world of science is still uncertain an incomplete.
“Nothing can be known with certainty'; Is this statement true? Are you certain? In this essay I plan to show that nothing can be known with certainty, I will examine the truth and certainty of life and of humans, and prove that nothing can be known for certain.
The major strength of science is that it has uncertainty and skepticism. Science never claims to be hundred percent accurate. There is always some degree of ambiguity and probability in science. The Heisenberg’s uncertainty in quantum mechanics is a good example of this. According to the Heisenberg’s uncertainty, we can never be sure of the position of the quantum particles. There is always a degree of fuzziness in nature and a fundamental limit to what we can understand about these particles and their behavior. We can only calculate the probability of the nature of the particle and ho...
Logic and mathematics starting with basic arithmetic showed me how to follow steps, one at a time and one after another, to arrive at the results, one step at a time and after another. I learned that an error in one step will make all the following steps and results wrong. Mathematics like any other rule and pattern based discipline may show through experience and trial or error, how to solve problems first by following given methods and later, if needed, by combining and exploring different methods.
