Creativity is a complex neuro-psycho-philosophical phenomenon which is difficult to define literally. Fundamentally it involves the ability to understand and express novel orderly relationships. The creative process involves four stages--preparation, incubation, illumination and verification. ⋯ Dopaminergic pathways are involved in the novelty seeking attitude of creative people while norepinephrine levels are depressed during discovery of novel orderly relationships. The relationship between mood and catecholamines and that of creative cognition is often in an inverted U-shaped form. It is hypothesized that that subtle frontal dysfunction is a pre-requisite for creative cognition but here again the relationship is also in an inverted U-form.

In a recent series of polemical editorials in this journal, a scathing and much needed criticism is made of many aspects of current scientific mores, detecting some worrying dysfunctions which threaten the integrity of the whole scientific enterprise. Although the tone is a bit hyperbolic, many important issues are addressed, such as honesty in research, the centrality of truth in science, the role of creativity, just to cite a few. Though agreeing with the overall diagnosis, the discussion still suffers from a lack of a clear and systemic view of science, from which a more precise analysis could be carried out. ⋯ In this paper we address these shortcomings with the aim of contributing to a better understanding of this timely discussion. Though conceding that major structural, historical and cultural shifts might have caused irreversible changes on the way science now evolves, we make some suggestions to counter this trend. These include, among others, the need for an honest and careful dealing with the media and public, to prize and abide by the ethos of science and its underlying values, to cultivate an exact philosophy and to insist that disinterested curiosity and the desire to understand the world are the vital motivations of science.
