What is the difference between premises and an assumption?
A premise is a statement, presumed to be true, on which an argument is based. An assumption is an unstated premise. For example, in the statement, “We have a global imperative to reverse global warming,” the assumption is that global warming is harmful in some way, even though that premise isn’t stated explicitly.
What is an assumption in logic?
A logical assumption is simply an idea that can be inferred, or identified, in a text without the writer stating it in an obvious way. One simple example may be the logical assumption that if you do not turn in your homework, your teacher will be disappointed in you.
What is a premise in logic?
Premise: Proposition used as evidence in an argument. Conclusion: Logical result of the relationship between the premises. Conclusions serve as the thesis of the argument. Argument: The assertion of a conclusion based on logical premises.
What is the difference between conclusion and assumption?
A conclusion is more definitive and an assumption is something you infer (deduce). So an assumption is more likely to be fallacious, that being said even a conclusion can be fallacious… :D.
How do you identify an assumption?
One of the most reliable ways to find assumptions is to look for shifts in language between the premises and conclusion of an argument. When new stuff appears in the conclusion that wasn’t discussed in the premises, it usually got there by way of an assumption.
How do you identify a premise?
If it’s being offered as a reason to believe another claim, then it’s functioning as a premise. If it’s expressing the main point of the argument, what the argument is trying to persuade you to accept, then it’s the conclusion. There are words and phrases that indicate premises too.
What is assumption in passage?
Assumption is a statement which must be true, for the given information to be true; in other words, for the conclusion to hold true. An inference can always be logically deducted from the given information. An assumption can never be logically deducted from the given information – It contains some new information.
Do you assume a premise in an argument?
However, you assume a premise for the purpose of an argument and the premise is explicit. And assumption is usually understood as a proposition taken for granted or accepted as true without proof. It is routine for philosophers to talk about looking for hidden assumptions. Suppose your conclusion happens to be falsified one way or the other.
What are premises and assumptions?
Premises are those statements on which the conclusion of the argument depends, that is, the “if” part, provided the argument is of the form “If A1, A2., hold, then B holds”. Of course, we also have tautologies which don’t depend on any premises. Assumptions are hypotheses made in the process of a proof which may be discharged later on.
What is a premise in philosophy?
First of all, a premise is a statement. As such, a premise is therefore explicit. A premise is a statement which is assumed as true for the purpose of an argument, where the conclusion will be considered as following from the given premise (see note on assume ). As such a premise may be actually true or actually false.
What is the meaning of premises?
