Emotions, feelings and morality play a critical role in our daily decision-making. With the rapid advance of industry and technology, however, this subjective information is becoming less valued in critical decisions. Rational thought and the accumulation of objective knowledge are often credited with humanity's thriving success in recent centuries. This book makes the case that humanity's social progress has only been possible through these oft-forgotten subjective factors, and will be equally crucial in altering the present course of society.
