It is the height of folly to pontificate to others on how properly to live, and only a fool would presume to do so. With that in mind, lets get started.
All but the most libertine of us embodies at least some of the moral baggage of others. History, society and culture all etch their ethical expectations on our souls. Do you feel pangs about indulging in pleasure? 
An overriding obedience to rules and institutions? A slavish devotion to work at the expense of things in life you know in your heart are more important? These and more are some of the more common involuntary burdens. For the moment lets wipe the slate clean of expectations and imagine what a life well lived might look like from first principles.
Those dispensing moral precepts often rely on some universal authority like religion or God. But if we are calling on the universe for rhetorical backup, let’s consider what the cosmos might really consider rare and valuable. As far as we know, in the entire galaxy and beyond, the conscious perception of reality is something that exists only here.
Perception is the culmination of billions of years of finely tuned cosmology and patient evolution here on Earth. Many theorists believe that observation somehow snaps the fuzzy world of quantum probabilities into what we perceive as reality. Other leading scientists have even coined the phrase perceptonium to describe a potential new state of matter that resides in our brains as the seat of consciousness.
In the absence of any other higher purpose, lets imagine that the Cosmos craves perception, of all kinds. Provable? Of course not. But at least there is compelling and unlikely evidence to support this as a guiding observation, if not a higher purpose. And in the words of Douglas Adams such a guiding observation would at least be “mostly harmless”.
There is a certain elegance in imagining creation fine-tuned in such a way that eons after her own birth, her precious and diverse offspring across the cosmos finally open their eyes to revel in her beauty for the first time – a celestial mirror billions of years in the making.
English is a wonderfully feral tongue, receptive over the centuries to creative additions as needed. I humbly now offer my own. Vidoraty is not a real word nor a pretty one but describes these themes better than any I have found so far. Rooted in Latin words videre to see, and adoratio for worship this might be a start. Consider this an open source effort – if you can suggest something better, please do.
So where does that take us? This gentle chisel blow cleaves life in some interesting moral directions. Like all members of this exclusive cosmic club, each one of us is entrusted with a sacred role in the eyes of creation. Keen senses coupled with our remarkable brain and creative imagination makes us perhaps the most exquisite perceivers to yet appear in the universe. The vastness of space and short period of time we have had modern form and agency also means we are in many ways allowing creation to see itself for the first time in such vivid detail.
This spiritual framework also seems to square with what we know of the cosmos and unlike many bygone beliefs has the advantage of being universal. Self-aware perception anywhere else in the cosmos would be just as unlikely and miraculous. Likewise a self aware intelligence of our own technological making would become a member of the same very exclusive club, and hopefully see the spiritual value in our continued kindred existence. As the the great Lebanese poet Khalil Gibran famously observed, "Beauty is eternity gazing at itself in a mirror, But you are eternity and you are the mirror."
