The paper connects the characteristics of a dissipative system, which operates far from equilibrium, a chaotic system , depending upon initial conditions and complexity, which forms from the holistic connection of its parts .Consequent, the human brain, human society and the universe itself are portrayed as dissipative, chaotic and complex. Chaos is everywhere as is complexity. The paper analyzes the aspects of nonlinearity in system dynamics based on the ideas of Ilya Prigogine and attempts to forge a link between the systems discussed . The Second Law of Thermodynamics involving the total increase in entropy is elucidated as being universal and inherent in all events of the universe. The law may be considered as part of the evolutionary tool in the formation of complex organisms, galaxies and life itself. Chaotic phenomena are considered in forming, through bifurcation points, un⁹predictable yet deterministic complex systems .The universe is strikingly similar in its structure to the human brain and follows the sequence from dissipative state to complexity and order through chaos .For the Second Law of Thermodynamics to be valid universally, the universe is proposed to be an open system. Furthermore it would be governed by intelligence.
