@Leonard Fair, but in my experience, life is rarely binary. Just because passions push us, doesn't mean that rationality doesn't guide us. Or can't.

I once made the likeness that passion is the fuel. Rationality is the engine. Well, that time, I argued morality was the engine, but the allegory still works. With poor fuel, you won't get far even with a mastercrafted engine. But without a good engine, a potent fuel will probably destroy everything. You need both to get anywhere with either.

@Leonard Purity is a charade for pregnant virgins. And the alpha and omega for reductionists.

I'd prefer thinking of rationality as a tool. Unlike what Rousseau and his cronies did. And the more tools you have and have mastered, the more adept you will be. The better care you take of your tools, the sharper, more efficient they will be when you need them. Forsaking a tool is the same as crippling yourself. Well, in my opinion.

@Rosencrantz (Omg you quoted Schoppenhauer i want you to know that i also like his way to consider things.)

Okay, then rationnality is the name you give to the way we interpret things.

And I agree with you ! We always use some form of logic to understand the world around us.

But this logic isnt universal, and because it's not, then why do you call it a "tool" ? If it can be handled in different ways, its because of passion (aka "the person").

THEREFORE : everything is linked with passion.
