Definition: A strong argument is a non-deductive argument that succeeds in providing probable, but not conclusive, logical support for its conclusion. A weak argument is a non-deductive argument that fails to provide probable support for its conclusion.
We do have a common term for a good argument that has true premises. This is called “sound”. It is a useful notion when we are applying our logic. Here is our definition: Sound argument: a valid argument with true premises.
A deductively strong argument, then, is the best argument one can give for a conclusion. If you consider an argument that is valid and the premises are true, then you should accept the conclusion as true or reasonable.
Definition: A cogent argument is a strong non-deductive argument that has true premises.
Deductive argument: involves the claim that the truth of its premises guarantees the truth of its conclusion; the terms valid and invalid are used to characterize deductive arguments. A deductive argument succeeds when, if you accept the evidence as true (the premises), you must accept the conclusion.
In a strong inductive argument, if the premises are true, it would be highly unlikely that the conclusion would be false. A strong inductive conclusion contains reliable beliefs that are backed by strong evidence (even though there is no guarantee that the beliefs are indisputable).
Aristotle postulated three argumentative appeals: logical, ethical, and emotional. Strong arguments have a balance of all of three, though logical (logos) is essential for a strong, valid argument.
if it is a deductive argument, it should be sound (and, therefore, also valid); if it is an inductive argument, it should be strong; its premises should be relevant to the conclusion; and it should not be circular, contain a contradiction in its premises, or have a conclusion that is always true.
An argument consists of several parts, a thesis statement, transitions between introduction, body and conclusion, paragraphs that provide evidence supporting the argument, evidence and a conclusion. NOTE: It is unethical to exclude evidence that may not support the thesis.
The arguments are often named as follows: (1) argument from motion, (2) argument from efficient cause, (3) argument from necessary being, (4) argument from gradations of goodness, and (5) argument from design.
There are several kinds of arguments in logic, the best-known of which are "deductive" and "inductive." An argument has one or more premises but only one conclusion. Each premise and the conclusion are truth bearers or "truth-candidates", each capable of being either true or false (but not both).
Argumentum a fortiori (literally "argument from the stronger [reason]") (UK: /ˈɑː fɔːrtiˈoʊri/, US: /ˈeɪ fɔːrʃiˈɔːraɪ/) is a form of argumentation that draws upon existing confidence in a proposition to argue in favor of a second proposition that is held to be implicit in, and even more certain than, the first.
The use of data, statistical evidence, and sufficient support to establish the practicality and rationality of your claims should be the strongest element of your argument. To have a logically sound argument, you should include: A debatable and supportable claim. Logical reasoning to support your claim.
wrangle, bickering, discord, dissension. in the sense of assertion.
TRUE: If an argument is sound, then it is valid and has all true premises. Since it is valid, the argument is such that if all the premises are true, then the conclusion must be true. A sound argument really does have all true premises so it does actually follow that its conclusion must be true.
VALID: If all the premises are true, the conclusion follows with certainty. STRONG: If all the premises are true, the conclusion follows with high probability. WEAK: If all the premises are true, the conclusion follows neither with certainty nor with high probability.
The past tense of argue is argued. The third-person singular simple present indicative form of argue is argues. The present participle of argue is arguing. The past participle of argue is argued.
Modus ponens is one of the most commonly used valid forms.
There are a number of different types of arguments, including causal arguments, narrative arguments and evaluation arguments. Each has a different purpose, and using the right type of argument for the given situation will ensure you get your point across in a clear and confident manner.
Unlike a deductive argument, a strong argument can have a false conclusion even if it starts with true premises (strong arguments only make the conclusion probable, not certain). A cogent argument must have true premises. Cogency is strength plus true premises, so this one is self-evident.
For an argument to be cogent, the premises must be true. Thus, since strength does not guarantee true premises, it also does not guarantee cogency. Consequently, it is possible to have an argument that is strong but uncogent.
A cogent argument is one that the truth of its premise makes the conclusion more likely to be true than false. Example: 1. Most birds can fly.
