However, students understandably get confused early in the course because we use reason to find out the truth. We all want to have a successful life and make the right decisions that will lead to a successful life. Ideally we will learn or figure out the truth and then reason from what is true to what else is true, and make good decisions. As we will see below, we use this reasoning process everyday. Think about this point as you examine all the examples below and in C1.
One of the first concepts introduced in Chapter 1 is the process of an inference. An inference is the process of reasoning from what we think is true to what else is true. Important is that an inference is synonymous with the reasoning of an argument or what we call metaphorically a trail of reasoning.
A trail of reasoning example was given with the hat problem in Chapter 1. One trail: If there were 5 hats originally, and only three used on the heads of the prisoners, and the remaining hats were put into an empty closet, then we know that there are two hats in the closet.
Notice what we mean by a "trail" - if one thing is true, then another is true, and if that is also true, then something else is true. Notice also that simple arithmetic is a logical inference and predicts things we sometimes cannot see. We predict that there are two hats in the closet IF the closet was empty prior to putting the remaining hats in the closet.
All this terminology reasoning , inference , argument , premises and conclusion is just common sense in disguise. Today, no one can beat Best Buy's prices on the new Apple iPhone. Thinking about the Today-statement makes some think infer the So-statement. Is it logical? See below. We get what we think or hope is good information, we think about what it means, and infer what else we think we know.
Then we often act on our inferences. So for the term 'inference,' all we mean is coming to a conclusion about what we think we know from something else we think we know. What is an Assumption — Definition, Features, Examples 2.
What is an Inference — Definition, Features, Examples 3. Assumption, Inference, Logical Reasoning, Tests. An assumption is something we usually take for granted or presuppose. It may be something we have already learnt and do not question. It can also be a part of our beliefs. We always assume our beliefs to be true and use them to interpret the world around us. However, this is only your belief. Skill in deciphering arguments made in ordinary-language is highly useful overall, not just in understanding philosophical texts.
This quiz allows you to practice the basic argument-recognition skill of differentiating between premises and conclusions. Privacy Policy. Skip to main content. Unit 1: Logic. Search for:. What is the argument trying to prove? There can be only one conclusion in a single argument.
The foolproof way to do this is to ask yourself what the author of the argument is trying to get you to believe. The answer to this question is the conclusion. You should also study very carefully the lists of premise and conclusion indicator words on page 3 in the text. There will not always be indicator words, though more often than not there are. You should note as well that the conclusion can often be identified as the statement directly before a premise indicator. Remember that these are general rules only.
Think of indicator words as "red flags. Then do exercises 1.
