This paper proposes that the human mind in its creativity and emotional self-awareness is the result of the evolutionary transition from sexuality to eroticism. Eroticism is arrived at and defined by the high amount of energy displayed in animal sexuality. We propose that the unique human emotional intelligence is due to this "overflow" of mating energy. What from the survival viewpoint looks like an enormous waste of time and energy reveals itself to be an unexpected psychological benefit. The diversion of sexual energy from procreation-a process that results in erotic fantasies-turns intimacy into a source of human self-consciousness. This places different emphasis on the meaning of eroticism and provides a coherent scenario of mental development beyond mere cognitive capacities. Arguments are presented on how erotic imagination, or sexual excitation as an end in itself, promotes the human propensity for explorative curiosity; data from ethology, psychology, sociology, and neuroscience are presented to support these arguments. As philosophical anthropologists, we do not provide new empirical data, but the available results of comparative behavioral research confirm our hypothesis.
