Chapter 1

Humans: The Complexly Simple Animal

 

 We are told - and I believe - that no two people on earth are identical. There are over eight billion variations of our single species. For that matter, you are not the same person you were yesterday. Your body is composed of trillions of cells working, more or less, in harmony to sustain your life. Your brain (with about 86 billion neurons) has the capacity to perform complex tasks. You can read and comprehend these words. You may have a gift for planning large social events, playing a musical instrument, and driving a car while avoiding countless obstacles along your route. I suspect your imagination can picture worlds you’ve never experienced, be they in the past, the future, or a distant galaxy.  Perhaps you have developed technical skills you will use to build a superior AI engine, discover a cure for Alzheimer's, or design a skyscraper that is taller than the Burj Khalifa. Even if you won’t do any of these last three things, a fellow human being will.

 But maybe a brilliant scientist won’t develop a new cure for toe fungus because their primitive emotions, like lust, or cognitive shortcuts, like confirmation bias, derail their efforts. Biological impulses like pleasure, hunger, and fear direct much of our behavior. Our simple need for security, love, and recognition is a powerful motivator of complex lives. So, in many respects, we are common and often predictable creatures beneath our infinite variability.

 We live in a highly complex society with laws, religions, politics, technologies, and infrastructures that have evolved over many generations and whose complexity can boggle even our brilliant minds. Yet many of our creations arose from simple psychological mechanisms such as the desire to belong to a group or to leave an enduring legacy.

 The reality is that we are a beautiful paradox. The aspiration of this book is to help us understand, celebrate, and master both the simple and complex aspects of ourselves. Succinctly put – our shared Human Nature.

 Let’s begin our journey with a survey of some elements of our human nature categorized to capture biological, psychological, emotional, social, and moral dimensions. These are traits or tendencies that occur across cultures and individuals, though they may manifest differently.

  • Fear of death – awareness of mortality and its implications
  • Desire for legacy – urge to leave a mark or be remembered

 These elements are not universally expressed in the same way, but they appear repeatedly across time, place, and culture. Together, they form a complex picture of what it means to be human.

 In the remainder of Part I of this book, we will take a macro look at human nature and address some oft-debated questions regarding the duality of our body-mind, the nature of consciousness, and our competing human natures of kindness and cruelty. In Part II, we will dissect Human Nature into its various components from our perceptions (and their limitations), through our memory, beliefs, values, knowledge, and intelligence, then our needs, motivations, and behaviors, and finally to considerations of our identities (Part III) and relationships (Part IV). In Part V, we will pause to consider how the preceding elements manifest in our lives. In Part VI, we will revisit these qualities of human nature and propose ways to navigate the pitfalls of life that threaten our survival as individuals and as a species. Of course, there will be some side trips along the road. I hope you find the journey informative and interesting. Please buckle up.
