"Personality is composed of two fundamentally different types of traits: those of ‘character;’ and those of ‘temperament.’ Your character traits stem from your experiences. Your childhood games; your family’s interests and values; how people in your community express love and hate… innumerable cultural forces build your unique set of character traits. The balance of your personality is your temperament, all the biologically based tendencies that contribute to your consistent patterns of feeling, thinking and behaving. As Spanish philosopher, Jose Ortega y Gasset, put it, ‘I am, plus my circumstances.’ Temperament is the ‘I am,’ the foundation of who you are."
~ Biological anthropologist Helen Fisher in This Will Make You Smarter, a fantastic collection of short essays by 151 big thinkers, who each answered the question, “What scientific concept will improve everybody’s cognitive toolkit?” (via curiositycounts)
