It is true induction, coming up with the strongest possible explanation for the phenomena he observes.Д¬onsider his description of how, upon first meeting Watson, he reasoned that Watson had just come from Afghanistan: Although he pretends that his knowledge is of the black-or-white variety, it often isnвЂ™t. He is a careful observer who processes what he sees to reach the most likely conclusion in the given set of circumstances. The fictional character Sherlock Holmes is a master of induction. вЂњThe weight of evidence for an extraordinary claim must be proportioned to its strangeness.вЂќ - Laplace, ThГ©orie analytique des probabilitГ©s (1812) Reasoning by Induction Once again, this is unreliable, as people may be biased and there may not be any direct evidence to support their testimony.

Testimonial evidence - When an individual presents an opinion, it is testimonial evidence.

For example, seeing a light in the sky and concluding that it is an alien aircraft would be argumentative evidence.

However, this evidence is unreliable when the facts are not directly testing a hypothesis.

Argumentative evidence - We sometimes draw conclusions based on facts.

The main use of anecdotal evidence is for forming hypotheses which can then be tested with experimental evidence.

Anecdotal or circumstantial evidence - Overreliance on anecdotal evidence can be a logical fallacy because it is based on the assumption that two coexisting factors are linked even though alternative explanations have not been explored.

Direct or experimental evidence - This relies on observations and experiments, which should be repeatable with consistent results.

Several types of evidence are used in reasoning to point to a truth: For example, we do not have proof for the existence or non-existence of aliens, although proof does exist somewhere.Дeductive and inductive reasoning areВ both based on evidence. Some statements have an objective truth that we cannot ascertain at present. When it comes to reasoning, a correctly phrased statement can be considered to have objective truth. For example, ethicists accept that it is difficult to establish absolute truths concerning whether something is right or wrong, as standards change over time and vary around the world. In some areas, it is necessary to accept that truth is subjective. And bucket number three is human historyвЂ¦. Bucket number two is organic systems, 3.5 billion years of biology on Earth. ItвЂ™s all the laws of math and physics, the entire physical universe. What are the three largest, most relevant sample sizes for identifying universal principles? Bucket number one is inorganic systems, which are 13.7 billion years in size. The more evidence we have, the stronger our conclusion can be. In general, we can consider something to be true if the available evidence seems to verify it. Although weвЂ™re still waiting for an answer, this doesnвЂ™t have to stop us from improving how we think by understanding a little more. Yet truth isnвЂ™t always as simple as weвЂ™d like to believe it is.ДЇor as far back as we can imagine, philosophers have debated whether absolute truth exists. The essence of reasoning is a search for truth. ThatвЂ™s logic.вЂќ - Lewis Carroll, Through the Looking-Glass вЂњContrariwise,вЂќ continued Tweedledee, вЂњif it was so, it might be and if it were so, it would be but as it isnвЂ™t, it ainвЂ™t. WeвЂ™ll dive into inductive and deductive reasoning as well as a bit of history.

This article explores truth - what it means and how we establish it. The question of what makes something true is more relevant than ever in this era of alternative facts and fake news. Lawyers cannot prove that something happened (or didnвЂ™t), but they can provide evidence that seems irrefutable. Scientists cannot prove a hypothesis, but they can collect evidence that points to its being true. Ok, letвЂ™s dig in and see what we can learn.ДЄs odd as it sounds, in science, law, and many other fields, there is no such thing as proof - there are only conclusions drawn from facts and observations.

Learn the difference between the two types of reasoning and how to use them when evaluating facts and arguments. You canвЂ™t prove truth, but using deductive and inductive reasoning, you can get close.
