This paper is written for the purpose of investigating the possibility of mutual illumination of literature and neuroscience. One of the most remarkable achievements in the field of neuroscience over the past decades is the discovery of dopamine. It is called "reward neurotransmitter", because it is released in our brain when we feel pleasure by accomplishing a given task and expecting some reward. Because of this nature, dopamine is usually related to the phenomenon of "flow"(a term by Dr. Csikszentmihalyi), an optimal experience, a total immersion in something. When we are in flow, we attain the state of total absence of ego, time, the boundary between self and the world, the boundary between the subject and the object which the subject is doing. In this state of mind, we feel the unprecedented ecstasy, the genuine beatitude. This definition of flow is perfectly well illuminated in Doctor Zhivago. Zhivago gets himself absorbed in writing poems after he and Lara arrive at the remote town of Varykino. He becomes unconscious of himself, he dose not notice the passing of time. He even feels that the boundary between the self and his work is relieved. In this state of flow, he feels that not he, but the language itself begins to think and speak for man. He shouts at the peak of beatitude "Lord, why hast Thou given me so much?" Although Pasternak knows nothing about dopamine, he offers to us all the details of dopamine-related state of mind. From this we may suppose that literature and science can communicate with the purpose of proving their alliance both possible and productive.
