logically

Change is the only constant.
Some changes are better.
All constants are better.

This would be an invalid syllogism. Logically, not all changes are constant. Since only some changes are better; this does not necessitate that the constant is better. It COULD be, but it also might NOT be.

Logic sucks.

This is because logic most purest form is a completely abstract concept. Abstract concepts can only exist in the philosophical realm. The concepts cannot enter into the physical realm without putting on the heavy concrete clothes which adds or possibly removes aspects from the original concept. Thus, logic can not exist in the physical realm.
Unfortunately, while the above syllogism is invalid logically; it is reality. Not saying that every that is constant is a better alternative, but everything that is constant is something which is better than nothing. Even if the nothing, seemed better than the something. However, bad you wanted the nothing to be something; sometimes it turns out to be nothing but at the same time something.

P.S. I've missed posting... but not all posting is missing... ergo I equals missing?
