The Russell Stannard Questions: Life

The following questions (Q) are taken verbatim from those poised by Russell Stannard in his 2010 book The End of Discovery [are we approaching the boundaries of the knowable?]; Oxford University Press, Oxford. I consider these typical of the sorts of modern Big Questions that are part and parcel of the philosophy of modern science, especially physical science.

My answers are based mainly with the thought of our being in a Simulated (Virtual Reality) Universe that has been constructed by one or more Supreme Programmers. However, some of the answers apply regardless of what the nature of our ultimate reality is.

Q. Why is the universe life-friendly?
A. The universe is both bio-friendly and not bio-friendly. 99.999% (add a few more 9’s here) of the cosmic environment is decidedly bio-unfriendly and would snuff you out so quick-smart you wouldn’t know what hit you. Of course the cosmos is also bio-friendly otherwise you wouldn’t be here reading this. If you reject a supernatural explanation, that leaves coincidence, a multiverse, or software. Coincidence is stretching things since there are just so many dials that have to be set to a very narrow range. The multiverse appeals to probability statistics – think of those millions of monkeys at millions of typewriters one of whom will type “Hamlet” word-for-word – eventually. That leaves software, or in other words a Supreme Programmer programing our universe in a bio-friendly way. 

Q. Is there extraterrestrial life, and if so, how do we humans stand in comparison as regards intellectual capacity?
A. Given the vastness of the cosmos, and the sheer number of galaxies in the observable cosmos, and the numbers of stars per galaxy with associated solar systems and the number of planets per solar system not to mention possible rogue/orphan planets and how interstellar cosmic organic chemistry associated with life is, well, cosmic, etc., you would have to be pretty brave to bet the family farm arguing Planet Earth being the proverbial cosmic IT when it comes to life. Even going up the chain from the origin of life ‘living’ molecules to unicellular life to multicellular life to intelligent life to technologically advanced life forms and advocating extreme difficulty in getting from one step to the next step on up the line, there must be – if you’re a betting person – millions of advanced extraterrestrial civilizations throughout the cosmos and a goodly number in our galaxy too. Further, we humans are the new boys on the block, so the odds are that any other extraterrestrial intelligences will have been around way longer that we have, and thus have evolved greater intellectual capacity that we have yet achieved. However, the interesting bit is that once intelligence is achieved, natural selection gives way to artificial selection, and part of that artificial selection might ultimately be the transition from biological intelligence to artificial intelligence, artificial intelligence which will further evolve via artificial selection as machine intelligence designs ever better machine intelligences.

Natural History: Some More Random Rambling

Sometimes you have a new thought, an idea, or eureka moment, but it’s not gutsy enough to expand into a reasonable length article or essay. So, here’s a further potpourri of thoughts on or about natural history that are too good not to record, but with not enough meat available to flesh out. 

oooooOOOOOooooo

* There are probably as many different definitions of “what is life?” as there have been and are biologists, life scientists, naturalists and philosophers, etc. Most centre on or around concepts like growth, reproduction, response to stimuli, metabolism, violations of the second law of thermodynamics (entropy), and related similar ilk. None have been entirely satisfactory otherwise we would have THE textbook definition. My take on “what is life?” is somewhat different. Life is some sort of complex organic structure that has a behaviour that is not absolutely predictable via classical (or even quantum) physics. Or, in other words, under the most tightly controlled and uniform set of laboratory conditions, the ‘structure’ will do as it damn well pleases!

oooooOOOOOooooo

* Speaking of life, there is no such thing as ‘living matter’ vs. ‘dead matter’. All matter is ‘dead matter’ since all matter, from the ground up, is composed of electrons, protons (quarks and gluons), neutrons (more quarks and gluons), photons, neutrinos, etc. Few if any would ague that an electron, proton, neutron, etc. is ‘living matter’. And the atoms, hence molecules, even complex molecules they make up are not alive. No matter is alive or is ‘living matter’. What is ‘alive’ is the organisation, the overall structure of various bits and pieces of matter, in highly specific arrangements, such that – and this is the key point – entropy, at least temporarily, is thwarted. Entropy finally wins when the organisational structure breaks down, that is, life dies.   

oooooOOOOOooooo

* Does free will require you to have an infinite or unlimited number of choices, or a finite number? If the latter, you’re still confined in a box, just a slightly larger box than if your box confined you to one and only one choice.

oooooOOOOOooooo

* The ultimate lack of free will associated with you is that you had absolutely no say in being conceived and being popped headlong into this world. You had no choice in your ancestry or in your genetics or your sex or even what historical era you were to make your way in. Now if you have absolutely no free will in these rather important, in fact absolutely fundamental, parts of your life being kick-started, why should you expect any free will from there on in?

Of course in some societies you’d have no choice in schooling or religion or upbringing or even to the person you got hitched to, etc. But all of that really falls under a separate category of sociology and culture and has nothing to do with the metaphysical or usual notion of what it means to have free will.

oooooOOOOOooooo

* It struck home to me recently how often we shift our worldviews. We have no worldview at birth. Our worldview at five is one that’s full of self, Santa Claus, the Easter Bunny, the Tooth Fairy, imaginary friends, and parties with lots of cakes, cookies, soda pop and presents. All of that certainly changes, and drastically so, when you hit the teens when your worldview shifts to the opposite sex and sex and rebellion against all things adult. Maybe somewhere there’s an easing in period, a first stirrings, where you start to acquire a worldview of a God and heaven and angels and all things bright and beautiful (that’s probably imposed on you by parents and social mores. Then you get trust out (usually by choice) into the adult world that’s full of bills and responsibilities and employment and/or family life raising your own brats. During all of this you probably never really think of the ‘natural’ cosmic context you find yourself in. But that tends to come as you pass the half-way mark and start heading downhill. The Big Questions come more to the fore and you start to adopt a worldview that makes comforting sense away from the normal routine worldview of taxes and nasty bosses and your kids in trouble with the police again. Again, for most, that tends to revolve around God and heaven and angels, etc. But some people start thinking more outside the comforting religious box and more about space and time, and before and after, and finite vs. infinity and what non-religious Big Picture makes the most philosophical and logical common sense. And whatever specific you come up with can also shift as you reflect on your earlier reflections without end as new concepts and connections come into being or focus which you’ve got to ponder and fit into the master worldview jigsaw puzzle you’ve established.

oooooOOOOOooooo

* Death is not something to be afraid of. You experience dying, but not death since once dead, you have no existence and you need to have an existence, you have to be alive, in order to experience something, anything, even death. So you never experience death, only that up to but not including death.

oooooOOOOOooooo

* There’s one absolute reason I’m convinced telepathy doesn’t exist. As I go about my daily walkabout routine and associated observations, I’m forever passing out mental thoughts and images of what I think of many of the deadbeat drivers and other lesser forms of humanity I spy with my little eyes. My thoughts tend not to be very complementary to say the least. But since the lowlifes and rift-rafts haven’t ever proceeded to immediately stop their lowlife activities and drop what ever rift-raft things they were up to, to instead change direction towards me and beat me about the heat and body unto a bloody pulp for my unflattering thoughts, I conclude telepathy doesn’t exist. If it did, I doubt I’d be typing these thoughts now.  

oooooOOOOOooooo

* Humans call them weeds. Mother Nature calls them plants. So-called ‘weeds’ too have their place in the natural scheme of things. Stupid humans!
