Excerpts

“Life is not ‘one thing’ – rather, it has many potentially separable aspects.

Importantly, conscious level is not the same as wakefulness.

Rather, consciousness seems to depend on how different parts of the brain speak to each other, in specific ways.

‘To measure is to know.’

Tononi, who pioneered this approach, argues that consciousness simply is integrated information. This is an intriguing and powerful proposal, but it comes at the cost of admitting that consciousness could be present everywhere and in everything, a philosophical view known as panpsychism.

The classical view of perception is that the brain processes sensory information in a bottom-up or ‘outside-in’ direction. . The Helmholtzian view inverts this framework, proposing that signals flowing into the brain from the outside world convey only prediction errors – the differences between what the brain expects and what it receives. ..  A number of experiments are now indicating that consciousness depends more on perceptual predictions, than on prediction errors.

But just as consciousness is not just one thing, conscious selfhood is also best understood as a complex construction generated by the brain.

Our experiences of being and having a body are ‘controlled hallucinations’ of a very distinctive kind. It now seems to me that fundamental aspects of our experiences of conscious selfhood might depend on control-oriented predictive perception of our messy physiology, of our animal blood and guts. We are conscious selves because we too are beast machines – self-sustaining flesh-bags that care about their own persistence.”

The good life is the simple life.  

Through much of human history, frugal simplicity was not a choice but a necessity – and since necessary, it was also deemed a moral virtue. But with the advent of industrial capitalism and a consumer society, a system arose that was committed to relentless growth, and with it grew a population (aka ‘the market’) that was enabled and encouraged to buy lots of stuff that, by traditional standards, was surplus to requirements. As a result, there’s a disconnect between the traditional values we have inherited and the consumerist imperatives instilled in us by contemporary culture.  .. 

Living simply now strikes many people as simply boring.(It becomes imperative from environmentalism also now.)

But if our current methods of making, getting, spending and discarding prove unsustainable, then there could come a time – and it might come quite soon – when we are forced towards simplicity. In which case, a venerable tradition will turn out to contain the philosophy of the future.

It would be one thing to concede that science may never be able to explain, say, the subjective experiences of the human mind. But the standard take on quantum mechanics suggests something far more surprising: that a complete understanding of even the objective, physical world is beyond science’s reach, since it’s impossible to translate into words how the theory’s math relates to the world we live in. 

The theory only predicts what scientists may see at the instant of observation — when all the wave function’s latent possibilities appear to collapse to one definitive outcome — and provides no narrative at all for what particles actually do before or after that, or even how much the word “particle” is apropos to the unobserved world. The act of observation itself is then posited to somehow convert this nonsensical situation into the world we see, of objects having definite locations and other properties. 

“Success is nothing,” his father taught him. “Proper work is what counts.” (Bassi's)“Yes, it is like that,” he said. “The idea that there is truth and simplicity behind phenomena, if you wish, you can relate it directly to a faith in God that is a unity that gives rise to everything.”“The simple things in life are the more genuine ones,” he explained. “When a person is simple, he’s a better person.”“Even if the world is ultimately not understandable, there is no reason to believe we have hit the bottom with quantum mechanics.”

The article from Aeon on evolution discusses how it is not just about adaptation, the species shapes the environment too, not only sapiens, others too. Some detailed research material on earthworms (6000 varieties) is also discussed.

Some excerpts:

"‘[T]he organism influences its own evolution, by being both the object of natural selection and the creator of the conditions of that selection,’ as the evolutionary biologists Richard Levins and Richard Lewontin put it."

"Researchers need to understand not just how niche construction evolves through natural selection, but how the environmental sources of natural selection are themselves transformed by niche construction."

The discovery of Higgs Boson and gravitational waves were no ordinary triumph of physics and confirmation of scientific predictions made rather speculatively. The laws of physics hold true and explain natural phenomena rather consistently.But, there are riddles that daunt physicists. ".. we have no idea what actually happened at the beginning of the Universe; if it was inflation, what was driving it; how it came about; and how it ended. If what happened at the beginning of the Universe is a mystery, what’s happening now is no less puzzling."We know little about dark matter which outnumbers ordinary matter by a factor of six to one. So with dark energy that accelerates the expansion of the universe. "These three puzzles – how the Universe began, what dark matter is, and what dark energy consists of – make a compelling science case for future. ..  there remains a possibility that all we’ll attain is yet more confidence that there’s some form of dark matter, some form of dark energy, and that the beginning of the Universe did undergo inflation. But we still won’t know what the dark matter or dark energy is, or what drove inflation. We’ll have a much more precise statement about our ignorance but nothing more."

In this field, scientists work 'not pushed by experiments but pulled by imagination.’ "They come up with possibilities – such as a huge family of new particles, or the notion that space-time should have more than four dimensions. Or even more exotic proposals – eg, that space-time doesn’t really exist as such, and instead emerges from the relationship between the quantum building blocks of the Universe.""While the hardcore theorists are driven by lofty ideals, the phenomenologists are more practical and crave a more immediate connection with the observed Universe."

".. there’s no clear guide, apart from personal or aesthetic inclinations about how to choose the correct solution."" there’s a limit to how much of the whole sky we can observe, and how far we can look back in time."".. a sound principle is to keep your eyes on the fundamentals, being careful not to jettison the things we know to be true.""There’s a glorious history of research in fundamental physics driving technological change – forcing researchers to come up with ingenious new devices and experiments that allow them to measure elusive phenomena."Einstein: ‘Let the people know that a new type of thinking is essential if mankind is to survive and move toward higher levels.’
