Most people tend to sound "logical" until you put what they say in premise form.
Basically, there are only 5 premise types which are important to remember, because most conversations can be converted into one of these 5:
1. If A, then B.
2. Only if A, then B
3. A includes B
4. A equals B
5. A or B
For example, some person might say "I like candy because it tastes nice."
Sounds like this sentence makes sense?
Lets put it in premise form.
If something tastes nice, then I like it.
Poison can taste nice, but you wouldnt like poison.
Thus the sentence is completely retarded.
One might defend that the actual premise only applies to candy, in a sense:
If candy tastes nice, then I like it. Candy tastes nice. I like it.
But candy can contain poison, thus then you wouldnt like it since you would die in pain from it even if it tastes nice while eating it, which makes the premise false again.
If you knew candy was poisonous and someone forced you to eat it, then you wouldnt like it at the time of eating even if it tasted nice.
Also, if you ate too much candy, then you wouldnt like it anymore since you would become ill even if it tastes nice to continue eating.
Also, if you have too much candy, it might even stop tasting nice, which negates one of the premises mentioned.
So we see that sentences used in common conversations are actually completely retarded and make no sense. The logic which can only exist if certain logical laws exist already turns most of daily conversations into rants of retards.
Basically, actual logic can only be built with premises which cannot be questioned in any way.
But due to the fallacy of logic, any premise can be questioned into infinity because every premise demands some other premise to prove itself.
Some premises are of course, still better than others in terms of consistency or lack of examples which refute them.
However, most premises in common conversations are retarded.
