We were shaped by individual selection to be selfish creatures who struggle for resources, pleasure, and prestige, and we were shaped by group selection to be hive creatures who long to lose ourselves in something larger. We are social creatures who need love and attachments, and we are industrious creatures with needs for effectance, able to enter a state of vital engagement with our work. We are the rider and we are the elephant, and our mental health depends on the two working together, each drawing on the others’ strengths.
