Philosophers don't just make claims, they give arguments/5(20). A Guide to Arguments. A critical tool in philosophy is logic. Any good argument on any topic in philosophy proceeds from premises that we think are quite likely to be true to substantive conclusions about humanity, the world, and our place in it by way of valid arguments.

Etymology[ edit ] The Latin root arguere to make bright, enlighten, make known, prove, etc. Informal logic and Formal logic Informal arguments as studied in informal logic, are presented in ordinary language and are intended for everyday discourse.
Conversely, formal arguments are studied in formal logic historically called symbolic logic, more commonly referred to as mathematical logic today and are expressed in a formal language.
Informal logic may be said to emphasize the study of argumentationwhereas formal logic emphasizes implication and inference. Informal arguments are sometimes implicit. That is, the rational structure — the relationship of claims, premises, warrants, relations of implication, and conclusion — is not always spelled out and immediately visible and must sometimes be made explicit by analysis.
Standard types[ edit ] Argument terminology There are several kinds of arguments in logic, the best-known of which are "deductive" and "inductive.
Each premise and the conclusion are truth bearers or "truth-candidates", each capable of being either true or false but not both.
These truth values bear on the terminology used with arguments. Deductive arguments[ edit ] A deductive argument asserts that the truth of the conclusion is a logical consequence of the premises.
Based on the premises, the conclusion follows necessarily with certainty. Deductive arguments are sometimes referred to as "truth-preserving" arguments.
A deductive argument is said to be valid or invalid. If one assumes the premises to be true ignoring their actual truth valueswould the conclusion follow with certainty? If yes, the argument is valid. Otherwise, it is invalid. In determining validity, the structure of the argument is essential to the determination, not the actual truth values.
If we assume the premises are true, the conclusion follows necessarily, and thus it is a valid argument. If a deductive argument is valid and its premises are all true, then it is also referred to as sound.
Otherwise, it is unsound, as in the "bats are birds" example.
Inductive arguments[ edit ] An inductive argumenton the other hand, asserts that the truth of the conclusion is supported to some degree of probability by the premises.
For example, given that the U. Arguments that involve predictions are inductive, as the future is uncertain. An inductive argument is said to be strong or weak. If the premises of an inductive argument are assumed true, is it probable the conclusion is also true?
If so, the argument is strong. Otherwise, it is weak.If God already knows the choices we will make in the future, can we be free? Leonard Peikoff considers three arguments against philosophy, each purporting to show that one cannot live by a philosophy and be happy, either because a philosophy places you in opposition to the world around you or leads you to suppress your individuality and self, or because philosophical ideas are essentially useless in an adult’s daily life.
At the heart of philosophy is philosophical argument. Arguments are different from assertions. Assertions are simply stated; arguments always involve giving A lot of philosophy involves arguing about which theory provides the best hypothesis to account for our experience. Understand how arguments can be used in different ways Define the three key terms: argument, premise, and conclusion Realize solutions that can be derived from a philosophical argument.
