The Rational Man is a rational and pragmatic approach to relationship dynamics and the social and psychological foundations of intergender relationships. The book is a compiled ten-year body of work by author/blogger Rollo Tomassi of therationalmale.com. Rollo Tomassi is one of the leading voices in the globally growing, male-focused online consortium known as the Manosphere. The concepts of positive masculinity, the feminine imperative, plastic theory, operational social conventions and the basic psychological theory underlying the understanding of the game and the ideology of the "red pill" are outlined. Tomassi explains and expounds on the principles of cross-gender social dynamics and the underlying considerations behind them.
