What is the argument from silence fallacy and how does it impact the validity of a statement or argument?
The argument from silence fallacy occurs when someone assumes that a statement is true because there is no evidence or information to the contrary. This can impact the validity of an argument by making it weak or unreliable, as the absence of evidence does not necessarily prove the truth of a claim.
What's a fallacy and how can it impact the validity of an argument?
A fallacy is a mistaken belief or flawed reasoning that can weaken the validity of an argument. Fallacies can mislead people by making an argument seem convincing even though it is not logically sound. It is important to identify and avoid fallacies in order to have a strong and credible argument.
What is the difference between material validity and formal validity?
An argument is said to be formally valid if it is valid in virtue of its form. For example, the argumentAll men are mortal.Socrates is a man.Therefore, Socrates is mortal.is formally valid because its validity does not depend on its content (plug in any predicates [some limitations apply], the argument will still be valid). E.g.All pigs can fly.Wilbur is a pig.Therefore, Wilbur can fly.(Valid, but not sound, since the first premise is false!)Now, material validity is different in that arguments are valid but not in virtue of their form. Recall that validity is defined as 'no possible valuation which makes the premises true and the conclusion false'. So the following argument is also valid:John had a nightmare.Therefore, John had a dream.If you formalise this argument, it would be "Fa, so Ga", which is invalid (or following Alex Oliver's terminology, impure, for it has both valid and invalid instances). So there seems to be a gap between validity and formal validity (i.e. not all valid arguments are formally valid). That's what Buridan called 'material validity'.
What is a categorical error and how does it impact the validity of a statement or argument?
A categorical error occurs when the terms or categories used in a statement or argument are not logically related or do not align properly. This impacts the validity of the statement or argument because it introduces a flaw in the reasoning, making it less reliable or convincing.
What factors contribute to the soundness of a deductive argument?

Which of these is a way to address a counter argument in a persuasive essay?
Acknowledge the validity of a counterargument, but highlight specific evidence that demonstrates the superiority of your argument
What is an invalid argument?
In invalid argument is one in which the premises do not necessitate the truth of the conclusion. An argument's validity or invalidity does NOT depend on the actual truth of the premises, just what they would entail IF they are true.
Is a valid argument strong or weak?
Valid arguments must include facts and supporting documentation in order to strengthen the validity. If not, then the argument can be challenged.
What is Systematic presentation of reasoning and supporting evidence that proves the validity of a statement or position?
Argument
How can I use a proof logic calculator to verify the validity of a logical argument?
To verify the validity of a logical argument using a proof logic calculator, input the premises and conclusion of the argument into the calculator. The calculator will then use rules of logic to determine if the conclusion logically follows from the premises. If the calculator shows that the argument is valid, it means the conclusion is logically supported by the premises.
Are Valid arguments strong or weak?
A valid argument is certainly stronger than an invalid argument. but an argument can be valid and still be relatively weak. Validity and strength are not the same, although they are both good features for an argument to have.
