My first duty to write a gripping yarn. Second is to convey credible characters who make you feel what they feel. Only third comes the idea.
David BrinThe measure of (mental) health is flexibility (not comparison to some 'norm'), the freedom to learn from experience ... to be influenced by reasonable arguments ... and the appeal to the emotions ... and especially the freedom to cease when sated. The essence of illness is the freezing of behavior into unalterable and insatiable patterns.
David Brin
