This article’s premise is that upon reflection, logic is everyone’s preferred method of decision making – even illogical arguments use logically sounding statements to appear more valid. To understand why, and how to make better decisions, consider that the “Truth” of something is not affected by anything but its actual truth. – All the points above about how truth is not determined. However, logical arguments should have a lot in common with proofs, even if they’re not quite as clear cut. So: Suppose that “1+1” equals 2. Often times, multiple choices are presented, but it isn’t clear if the best decision is choice #1, choice #2, or some other choice not considered at all. Try insering “1+1=3” in place of the elipses (…) – how do any of these statements affect the actual truth? Well, prior to the relative viewpoint becoming dominant, there was a geocentric viewpoint. Costs would be outrageous, and there is always the risk of irreversible damage (environmental crisis, climate change, nuclear war). Indeed, nothing – including what you are now reading, or even your own apprehension, doubt, or rejection of the principles of logic – can change it. To live the lifestyle we are accustomed to, we rely on others to handle at least some portions of our lives (eg, research, invention, technology, manufacture, legislation, etc), and by implication, to make reasonable decisions on our behalf. They were upset that random tourists who had never been to London before would now have just as much chance of boarding the train first. The most general applications are those to the study of language. These seem like quite different concepts at first blush. Good salesmen know that face-to-face meetings are far more effective than email – is the same person more “trustworthy” or “credible” depending on their proximity? Perhaps for now, the most important change we can make to our thinking and decision making is simply recognizing that not only are we limited in terms of the available evidence to support our own strong opinions, but that the same applies to others, including those we trust and look up to. Logic gives form to reason by applying principles and rules that allow the mind to infer the validity of any statement. What’s more, when Galileo did suggest a model that better fit the data, he was punished. A powerful aspect of abstraction is that many different situations become the same when you forget some details. I am drawn to finding similarities between things, both in mathematics and in life. In the modern approach, with the scientific method more fully developed, scientists would be encouraged to question and look for flaws in existing theories. These are just “things”, with no distinguishable characteristics. How much conviction they speak with? – Inductive, empirical, hypothesis, theorem, theory, law, conjecture The mathematical world has been set up specifically to eliminate that uncertainty, but we can’t just ignore that aspect of real life. Perhaps just opening up our strongest, most closed-minded views to scrutiny through evidence, realizing that the strong, closed-minded ideas of others should be open to the same type of scrutiny, and thinking about what type of evidence could call these opinions into question, would be an enormous step forward. So this is where creativity comes in: What can we learn from smaller groups? Granted, in normal life we might not need to go there quite so explicitly in order to think logically about the world around us, but the process is still there when we are trying to find the logic in a situation. Unfortunately, truly good decision making requires expertise, at least in the area of decision making itself. We can use extremely secure building techniques, but if we use bricks made of polystyrene we’ll never get a very strong building. Applied logic - Applied logic - Applications of logic: The second main part of applied logic concerns the uses of logic and logical methods in different fields outside logic itself. Practical Logic and Decision Making in Real Life. Or is that just short-sighted thinking and a lack of imagination? To perform this abstraction well, we need to separate out the things that are inherent from the things that are coincidental. Unfortunately, humans are also born with the ability to think illogically, so the distinction between logic and non-logic is important. What if you hear it regularly? However, a scientist’s interpretation of “stuff we don’t know” is: “Stuff we should try to find out”, whereas the religious point of view tends to be “Stuff we can never know, so let’s not bother trying.”  This seems a shame. If you grew up believing something, does that affect its truth? Logic is one’s ability to define problems and solutions. This is not an explicitly mathematical example but this way of making analogies is the essence of mathematical thinking, where we focus on important features of a situation to clarify it, and to make connections with other situations.
