Though people often confuse/conflate them, beauty and health are not the same. It is entirely possible that a very beautiful person has some health problem (e.g., high cholesterol, osteoporosis, etc.) that gives them chronic or extreme pain, shortens their life, etc., which they hide from the world.
Social scientists often celebrate the diversity of cultures and languages in the world, because taken overall/comparatively, this diversity resists the negative aspects of globalization (e.g., corporate conglomeration and monopolization, the colonialistic imposition of wealthier or larger cultures on smaller or poorer ones, etc.) and offers a wide variety of ways of thinking about life.
However, most people are not social scientists; for most people, culture means ignorance. Most people don’t travel very far from home except perhaps for a very brief vacation or pilgrimage, just do a socially acceptable job, marry within their ethnic group and possibly social class, watch their people’s TV and movies, listen to their people’s music, speak their people’s language (thinking in terms of only one worldview, using words other groups can’t understand, etc.), eat their people’s food… and generally ignore or resist other societies and the natural world beyond their people’s territory.
People’s lives are small and brief, languages and cultures are complex and time-consuming to learn (sticking with the one you were raised with is easiest), and culture and language are tied up with people’s senses of self/identity. Culture+language is perhaps humanity’s most basic echo chamber, and most people seem trapped within one or two cultures, unable or unwilling to view their own existence differently.
If, as I understand Mahayana-based Buddhisms to teach, we are all really one big monistic/unified Mind/Being, which is supposedly happier as Itself than as a suffering human, why doesn’t one person’s becoming enlightened cause everyone to become enlightened? When the Mind learns of its delusion from one person (e.g., Gautama Buddha), why doesn’t It correct Itself and stop manifesting this world?
In the name of “critical thinking,” I have noticed a tendency in the West for intellectuals to become not only reflective and deconstructive, but to frequently live in mentally aggressive/hostile, cynical, pessimistic, etc. states of mind. Although I would agree that being overly positive can bias one in various ways (e.g., to see only what you want to see and miss/ignore challenges, obstacles, etc.), being overly negative can bias one in opposite ways (e.g., to see only obstacles or challenges and miss/ignore what might be possible). So I think it is important to turn critical thinking against itself, and to be critical of becoming too negative of a person. To me, the main value of critical thinking is to acknowledge and let go of biases and assumptions, to become mentally detached and aware, to try to see and think clearly. Mental detachment is perhaps the primary activity/aspect of mindfulness meditation, as is awareness of vipassana meditation.
In my experience, every large group, nation, etc. contains the full range of people, from terrible to wonderful. “They” are not all bad, and “we” are not all good. Please stop seeing the world in terms of simplistic categories, and start seeing the incredible complexity of life.
When I watch documentaries like these, I see beings who have cultures, languages, families, communities with both internal and external social structures and conflicts, technologies/tools, educational techniques, personal desires and attachments, who mourn their losses, and who have substantively the same body configurations as we do. There are a few key things they haven’t developed yet (e.g., preserving knowledge using artifacts, and using cooking to increase their calorie intake (hence brain neuron density) and to give them more free time), but those developments seem quite minor, and probably just a matter of time and opportunity, to me.
“…since Freud, the most extravagant fancies in the realm of love are considered to be perfectly normal (a person without them is regarded as a case for treatment), in the realm of death (the other great pole of human life) any strange fancies are still classed as ‘morbid’. The Suttas reverse the situation: sensual thoughts are the thoughts of a sick man (sick with ignorance and craving), and the way to health is through thoughts of foulness and the diseases of the body, and of its death and decomposition” (Ñāṇavīra Thera, “Clearing the Path”).
