what kind of fallacy is this?state a reason

All economics students are hardworking.....................1
All pharmacy students are hardworking.........................2
All economics and pharmacy students are hardworking.....c

Well the argument is valid.
P
Q
Therefore, P and Q.
However, this becomes a begging the question fallacy if it is presented as a justification for the claim "all economics and pharmacy students are hardworking" because all it does is re-state the conclusion in the premises.

This is a logically valid argument. Not a fallacy as Bo defines a fallacy. The two premises are unproven and no doubt that are factual errors.

The argument strikes me as invalid because the syllogism commits an illicit minor and then repeats itself
in the conclusion thereby violating the rules of proper syllogism.


The 8 rules of syllogism are as follow:

There should only be three terms in the syllogism, namely: the major term, the minor term, and the middle term. And the meaning of the middle term in the first premise should not be changed in the second premise; otherwise, the syllogism will have 4 terms.

The major and the minor terms should only be universal in the conclusion if they are universal in the premises. In other words, if the major and the minor terms are universal in the conclusion, then they must also be universal in the premises for the argument to be valid. Hence, if the major and minor terms are particular in the conclusion, then rule #2 is not applicable.

The middle term must be universal at least once. Or, at least one of the middle terms must be universal.

If the premises are affirmative, then the conclusion must be affirmative.

If one premise is affirmative and the other negative, then the conclusion must be negative.

The argument is invalid whenever the premises are both negative. This is because we cannot draw a valid conclusion from two negative premises.

One premise at least must be universal.

If one premise is particular, then the conclusion must be particular.

Hi, judyth!

Yes, the argument is undeniably valid. An argument is valid if and only if it is impossible for all of the premises to be true and the conclusion false. In terms of fallacies, I agree that the argument begs the question. This is a tricky evaluation to make because no singular premise assumes the conclusion; only when the premises are considered in unison does one then arrive at the conclusion, which in itself is not enough for it to be true that an argument begs the question. However, because the conclusion is just a conjunction of all the premises, I agree that the argument begs the question unless a contrary response is given with better reasons.

I don't see a fallacy.
A is true
B is true
A and B are both true is true.

There is no conclusion, just both premises are repeated, so it doesn't seem to be in the form of an argument. Not that it has to be an argument of course, but it seems pointless. Also there's no fallacy.
