Noteworthy expert in psychology and intelligence Robert J. Sternberg gives an innovative introduction to psychology, focusing on the evolution of ideas and dialectical thinking. This focus on the evolution of ideas is complimented by an examination of the evolution of organisms and the importance of adaptation to their environment. Sternberg's Triarchic Theory of Intelligence (analytical, creative, and practical) is implemented and includes questions embedded within chapters as well as at the ends of chapters. Use of the Psyche myth throughout the text emphasises continuity of thinking in psychology and exemplifies many of the phenomena that psychologists seek to study: curiosity, envy, love, compassion, altruism, and perseverance.
