 Living Things Renew Themselves

Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued a...

 Dawkin's Concept of Life

My vision of life is that everything extends from replicators, which are in practice DNA molecules on this planet. The replicators reach out into the world to influence their own probability of being passed on. Mostly they don't reach further than the individual body in which they sit, but that's a matter of practice, not a matter of principle. The individual organism can be defined as that set of phenotypic products which have a single route of exit of the genes into the future. That's not t...

 Oliver Sacks on Focus in the Last Months of Life

I feel a sudden clear focus and perspective. There is no time for anything inessential. I must focus on myself, my work and my friends. I shall no longer look at “NewsHour” every night. I shall no longer pay any attention to politics or arguments about global warming. This is not indifference but detachment — I still care deeply about the Middle East, about global warming, about growing inequality, but these are no longer my business; they belong to the future. I rejoice when I meet gi...

 Picard Defends Data as Life

Commander Riker has dramatically demonstrated to this court that Lieutenant Commander Data is a machine. Do we deny that? No, because it is not relevant: we, too, are machines, just machines of a different type. Commander Riker has also reminded us that Lieutenant Commander Data was created by a man; do we deny that? No. Again, it is not relevant. Children are created from the 'building blocks' of their parents' DNA. Are they property? [...] Your honor, the courtroom is a crucible; in it, w...

 Science Does Not Rob Life of Purpose

Presumably there is indeed no purpose in the ultimate fate of the cosmos, but do any of us really tie our life's hopes to the ultimate fate of the cosmos anyway? Of course we don't; not if we are sane. Our lives are ruled by all sorts of closer, warmer, human ambitions and perceptions. To accuse science of robbing life of the warmth that makes it worth living is so preposterously mistaken, so diametrically opposite to my own feelings and those of most working scientists, I am almost driven to...

 Darwin and the Origins of Life

There is a curious parallelism between Darwin's twenty-year delay in publishing his theory of evolution and Newton's {102} twenty-year delay in publishing the Principia. And Newton's refusal to publish his cosmological speculations finds a parallel in Darwin's silence concerning the problem of the origin of life. If we are to understand in general terms the place of life in the universe, we must also understand life's origin. Darwin explicitly excluded the origin of life from the scope of ...

 Life with Metabolism VS Replication

It is logically possible to postulate organisms composed of pure hardware, capable of metabolism but incapable of replication. It is possible to postulate organisms composed of pure software, capable of replication but incapable of metabolism. And if the functions of life are separated in this fashion, it is to be expected that the latter type of organism will become an obligatory parasite upon the former. This logical analysis of the functions of life helps to explain and to correct the bias...

 Life Reduced to Bad Physics

Those reductionists who try to reduce life to physics usually try to reduce it to primitive physics—not to good physics. Good physics is broad enough to contain life, to encompass life in its description since good physics allows a vast field of possible descriptions. There is no reason why living beings should be compared to primitive machines which don't make use of feedback.

 Life Emerges from the Second Law of Thermodynamics

Every species of living thing can make a copy of itself by exchanging energy and matter with its surroundings. One feature common to all such examples of spontaneous “self-replication” is their statistical irreversibility: clearly, it is much more likely that one bacterium should turn into two than that two should somehow spontaneously revert back into one. From the standpoint of physics, this observation contains an intriguing hint of how the properties of self-replicators must be constr...

 Life is Like a Sonnet

"In your language you have a form of poetry called the sonnet…It is a very strict form of poetry, is it not? …There are fourteen lines, I believe, all in iambic pentameter. That’s a very strict rhythm, or meter…And each line has to end with a rigid rhyme pattern. And if the poet does not do it exactly this way, it is not a sonnet, is it? …But within this strict form the poet has complete freedom to say whatever he wants, doesn’t he?” “You mean you’re comparing our lives to ...

It has a strict formula and structure, but it's what you do within the restrictions that is important.
