We are animals because we need to do things other animals do, like sleep, eat, we have a powerful urge to mate and reproduce to pass our genes on. We need sunlight and nature and use the bathroom.
Because we depend on our environment we must care for the environment as a means of caring for ourselves. We depend on our atmosphere to protect us from radiation and to breathe. We depend on plants to produce oxygen and recycle our carbon dioxide. We must live in a symbiotic relationship with the environment but we don't. We pretend it is purely at our disposal.
This is because our brain is so powerful. We have developed stories that are fantasies about our origins, such as believing we were created distinct from other animals because we somehow think we are special and thus these stories a tapestry of superstitions that are religion.
We depend on each other completely for our understanding of reality that we need contact with other human beings for our sanity and these stories we tell each other shape us into who we are.
We are clever animals who have evolved hands to be able to craft and utilize tools. We have also learned the value of communicating, storing and sharing information. Indeed, some of our landmark discoveries has been the storing and transmission of information, cave paintings, the Gutenberg press, math, telegraph, cinema, radio, television, computers and the Internet.
But our experience of reality depends largely on who and what we believe. And knowing what is fiction can be difficult if we believe it. It's nearly impossible to find the flaws in our own thinking (or believing) and this can make it difficult to communicate with others who don't believe what we believe. It's nearly impossible to be objective enough to see our own hypocrisy, even when we are aware we may have flaws in our own thinking. Since we attach so much importance to sanity it can be deeply distressing to find out our beliefs are wrong.
I used to know a born again Christian who delighted in telling me about her favorite t-shirt which said: Christians aren't perfect, just forgiven. She didn't realize this was her license to be completely immoral.
