- This is a list of common faulty arguments I often hear, along with explanations
- why they're false.
- 1. If we can't achieve perfection, we shouldn't try at all.
- e.g.: "People will never be completely equal, so communism won't work."
- We can practically never achieve anything perfectly, which however doesn't
- mean the effort is meaningless, because getting closer to an ideal goal is
- usually better than not getting closer to it. In fact, this is what we mostly
- aim for -- get as close to perfection as possible, even knowing perfection
- can't be achieved -- a great example of this is law, which we know will never
- be perfect, yet we also know we shouldn't abanndon the idea just because of
- this fact.
- 2. X is (un)natural (normal), therefore X is (un)desirable.
- This doesn't follow, because many things are natural and undesirable ("bad")
- and many other things are unnatural and desirable ("good") (the meaning of
- good/bad of course being dependent on the topic being discussed and further
- reasoning).
- Examples of potentially bad natural things: diseases, agony, bullying, ...
- Examples of potentially good unnatural things: science, houses, books, ...
- So with this argument you have to argue further why te property of being
- (un)natural implies (un)desirability.
- 3. Ad hominem: arguing against (for) an author of a logical argument instead of
- against (for) the argument itself.
- E.g. "He is a pedophile, so his idea should be rejected."
- Any idea that is supposed to be logically verifiable, i.e. a rational logical
- argument, is completely independent of its source, i.e. where it comes from.
- The source can only matter when the information is not a logical argment,
- i.e. it cannot be logically verified, e.g. a leaked inside information,
- a rumor etc.
- 4. It is his property, therefore he can do anything he wants with it.
- E.g. "The social network runs on his server, therefore he can censor whatever
- he wants on it."
- This is false because the scope of property rights (both legal or moral), as
- of any rights, have limits. For example if someone owns a gun, it generally
- is not his right to point that gun to someone else and pull the trigger,
- i.e. to kill the person, or if someone owns a sound system, it is not his
- right to play loud music with it in the middle of the night.
