The relationship between mental illness (or "madness," as Socrates labeled psychosis, as well as a wide range of states of thought and emotion [Jamison, 1993]) and creativity has been noted since before the times of Socrates. The questions that this noted relationship pose are significant. Famous authors, poets, artists, and musicians who suffered from various forms of mental illness are littered throughout history. Edgar Allen Poe himself noted, "Men have called me mad but the question is not yet settled, whether madness is or is not the loftiest intelligence \u2014 whether much that is glorious \u2014 whether all that is profound \u2014 does not spring from disease of thought \u2014 from moods of mind exalted at the expense of the general intellect." Only in recent years have researchers begun to classify these disorders of past artists using modern diagnostic measures. While the concept of a relationship between creativity and mental illness is fascinating in and of itself, understanding the implications of a possible correlation is essential to the care and treatment that individuals with the diseases are given. If, indeed, creativity is linked with affective disorders, what does this mean for the treatment of these disorders? By eliminating the symptoms of mood disorders, are we also inadvertently eliminating creativity? It is important to acknowledge the possibility that mental illnesses like bipolar disorder include benefits to those afflicted. How can we treat the negative symptoms of mood disorders while enhancing the positive symptoms? In order to conclude that there is a link between creativity and mood disorders, it is first necessary to reexamine and reestablish the processes by which mood disorders are diagnosed. Although currently diagnosed on a categorical scale \u2014 meaning the patient is diagnosed under the black-and-white category of manic or depressive at a given point in time \u2014 this paper will argue that mood disorders can be better diagnosed and treated on a continuum of mood states. Furthermore, by viewing mood disorders on such a continuum, writers like Anne Sexton and Sylvia Plath, whose diagnoses are debated by historians and professionals, can be established as having a diagnosable affective disorder, since both experienced symptoms of depression and mania, if not in the precise timing and manner proscribed by the Diagnostic Manual. Finally, by determining these writers' diagnoses, a relationship can be explored between their creative states and their mood states.
