Paul Davies Quotes

Seventy-five years ago Erwin Schrödinger published... ... the key point... was whether life can be explained by physics. ...Schrödinger ...said "We must be prepared to find a new kind of physical law prevailing..."

The thing that separates life from non-life is information.

To a physicist like me, life looks to be little short of magic: all those dumb molecules conspiring to achieve such clever things!

The laws of nature are rigged not only in favor of complexity, or just in favor of life, but also in favor of mind. To put it dramatically, it implies that mind is written into the laws of nature in a fundamental way.

In each and every one of us lies a message. It is inscribed in an ancient code, its beginnings lost in the mists of time. Decrypted, the message contains instructions on how to make a human being. Nobody wrote the message; nobody invented the code. They came into existence spontaneously. Their designer was Mother Nature herself, working only within the scope of her immutable laws and capitalizing on the vagaries of chance.The message isn't written in ink or type, but in atoms, strung together in an elaborately arranged sequence to form DNA, short for deoxyribonucleic acid. It is the most extraordinary molecule on Earth.

I cannot believe that our existence in this universe is a mere quirk of fate, an accident of history, an incidental blip in the great cosmic drama. Our involvement is too intimate.

Human beings have always been struck by the complex harmony and intricate organization of the physical world. The march of the heavenly bodies across the sky, the rhythms of the seasons, the pattern of a snowflake, the myriads of living creatures so well adapted to their environment – all these things seem too well arranged to be a mindless accident.

What is remarkable is that human beings are actually able to carry out this code-breaking operation, that the human mind has the necessary intellectual equipment for us to "unlock the secrets of nature"...

The scientific quest is a journey into the unknown.

Matter as such has been demoted from its central role, to be replaced by concepts such as organization, complexity and information.

That the universe has organized its own self-awareness – is for me powerful evidence that there is 'something going on' behind it all. The impression of design is overwhelming. Science may explain all the processes whereby the universe evolves its own destiny, but that still leaves room for there to be a meaning behind existence.

The brain is the medium of expression of the human mind. Similarly the entire physical universe would be the medium of expression of the mind of a natural God.

All this prompts the question of why, from the infinite rage of possible values that Nature could have selected for the fundamental constants, and from the infinite variety of initial conditions that could have characterized the primeval universe, the actual values and conditions conspire to produce the particular range of special features that we observe. For clearly the universe is a very special place: exceedingly uniform on a large scale, yet not so precisely uniform that galaxies could not form; extremely low entropy per proton, and hence cool enough for chemistry to happen; almost zero cosmic propulsion and an expansion rate tuned to that energy content to unbelievable accuracy; values for the strengths of its forces that permit nuclei to exist, yet do not burn up all the cosmic hydrogen, and many more apparent accidents of fortune.

Science, it is usually believed, helps us to build a picture of objective reality – the world 'out there'. With the advent of the quantum theory, that very reality appears to have crumbled, to be replaced by something so revolutionary and bizarre that its consequences have not yet been properly faced.

In the emerging picture of mankind in the universe, the future (if it exists) will surely entail discoveries about space and time which will open up whole new perspectives in the relationship between mankind, mind, and the uni-verse.… But what is now? There is no such thing in physics;it is not even clear that ‘now’ could ever be described, let alone explained, in terms of physics.… Notions such as ‘the past,’ ‘the present’ and ‘the future’ seem to be more linguistic than physical.… There is no universal now, but only a personal one—a ‘here and now.’ This strongly suggests that we look to the mind, rather than to the physical world, as the origin of the division of time into past, present, and future.…There is none of this in physics.… No physical experiment has ever been performed to detect the passage of time. As soon as the objective world of reality is considered, the passage of time disappears like a ghost into the night.
