I don't like the quote. It assumes that conflict (as presented by unreasonable behavior) is the only way to advance. Progress is, by definition, change and that means disrupting the known and comfortable situation for something else.<br />
But why do you have to be unreasonable about it?
What is unreasonable?
yes, the person who thinks ahead of into the future, the vast majority of people see as a person who is crazy.
Sure! I like that quote. For the most part, we're only able to judge reason based on what we've accepted as truth, so it takes someone who's willing to be crazy and stubborn in that context to think beyond/outside those constraints. Thank goodness for them.
