Darwin for Today: Inheritance, Compassion, and Responsibility

The chapter's central question

It is a great comfort to no longer see the excitement or sudden surprises before a presentation as just a lack of personal will. Your body moves quickly to prepare for possible danger. At the same time, there is no guarantee that older alerts accurately measure current, real risks, so we must respect the signals and reinterpret them to fit our environment.

Modern society forces emotional labor like emotionless professionals and robots who always smile. But Darwin's theory of evolution gives you warm comfort.

The pounding of my heart when I'm nervous isn't because my body is stupid, but because it's an extremely devoted loving response that pumps blood to my muscles and brain in full force to overcome the beast of upcoming exams and presentations.

Don't dismiss your fears and tears as pathological flaws. When we honor this trustworthy biological compass handed down to us by our ancestors over millions of years, we can regain deep peace in our bodies and souls.

Context and nuance

Darwin's 『Expression of Emotions in Man and Animals』 studied facial expressions and gestures not as created fixed symbols but as behaviors formed throughout the history of the species. Comparing babies, animals, photographs, works of art, and reports from different parts of the world, he argued for the continuity between humans and other animals.

The conclusion that ‘what is natural’ is ‘good’ is a naturalistic error. Jealousy and aggression may have an evolutionary history, but that does not justify the behavior. Rather than eliminating responsibility, understanding origins allows us to distinguish between automatic reactions and optional actions.

Do not oversimplify it this way

Knowing our evolutionary origins does not always make our current emotions useful or commands to follow. Reactions formed in past environments may be at odds with today's situations, and cultural learning and individual differences play a large role on universal trends. Darwin's historical data and the conclusions of today's emotional science must be read separately.

Philosophy in life

Have you ever felt so pitiful that the mere sound of a rustle in a dark alley made your hair stand on end and your heart pound like it would explode?

Arousal Reappraisal: When your heart is pounding like it's going to explode, say 'I'm anxious' instead of 'My body is pouring oxygen to my brain and getting ready to perform at its best!'
