Our desires are rational if and only if
{ 1 } - our desires promote basic human needs.
{ 2 } - we are factually informed.
{ 3 } - we highly satisfy the conditions for practical rationality.
{ 4 } - we are consistent about our desires.
{ 5 } - none of these -- desires can't be "rational" or "irrational."

This isn't a part of the theory. Our theory of rational desires isn't based on a theory of human needs. But a theory of human needs could perhaps be based on a theory of rational desires.

David Hume thought this; he said that it wasn't contrary to reason to prefer the destruction of the whole world to the scratching of his finger. He said this because he thought that this preference needn't involve any factual error. But it's difficult to imagine anyone satisfying our conditions for practical rationality and yet having this preference.
