It is a pet peeve of mine when people throw around arguments citing 'Fair Use' and yet fail to actually explain what a fair use argument actually is.

The sounder your argument, the more satisfaction you get out of it.

Where we desire to be informed 'tis good to contest with men above ourselves; but to confirm and establish our opinions, 'tis best to argue with judgments below our own, that the frequent spoils and victories over their reasons may settle in ourselves an esteem and confirmed opinion of our own.

He who establishes his argument by noise and command shows that his reason is weak.

It takes two to quarrel, but only one to end it.

A half truth, like half a brick, is always more forcible as an argument than a whole one. It carries better.
