The transcendent moment
What if the next stage of evolution was the slow rise of an understandable human voice among all life on the planet, speaking directly to you sometimes out of the blue.

Now I'm the dupe
Two points: we have no community. In the past many ran with groups of familiars in their generational cohort and through them met with similar groups and that was the medium through which strangers were made familiar enough to connect. It was much more organic. As a result, we've become atomized and in seeking to reconstruct that world, we've fit it into our screens. This results in reducing everything in our life to an interactive square within our glowing rectangle, our food lever within our Skinner box. Now, we're all a captured audience not unlike those dupes at the video poker in the gas stations in the muddy Midwest of my youth. Sad really, I've found myself more than once become that sun-leathered dupe, cigarette smoldering between lips, staring blankly at card choices, smacking away at the select/discard buttons like a monkey in an experiment.

Explaining life in terms of the statistical theory of entropy
"How would we express in terms of the statistical theory the marvellous faculty of a living organism, by which it delays the decay into thermodynamical equilibrium (death)? We said before: 'It feeds upon negative entropy', attracting, as it were, a stream of negative entropy upon itself, to compensate the entropy increase it produces by living and thus to maintain itself on a stationary and fairly low entropy level.
"If D is a measure of disorder, its reciprocal 1/D, can be regarded as a direct measure of order. Since the logarithm of 1/D is just minus the logarithm of D, we can write Boltzmann's equation thus:
- (entropy) = k log (1/D)
Hence the awkward expression 'negative entropy' can be replaced by a better one: entropy, taken with the negative sign, is itself a measure of order. Thus the device by which an organism maintains itself stationary at a fairly high level of orderliness ( = fairly low level of entropy) really consists in continually sucking orderliness from its environment. This conclusion is less paradoxical than it appears at first sight. Rather could it be blamed for triviality. Indeed, in the case of higher animals we know the kind of orderliness they feed upon well enough, viz. the extremely well-ordered state of matter in more or less complicated organic compounds, which serve them as food stuffs. After utilizing it they return it in a very much degraded form — not entirely degraded, however, for plants can still make use of it. (These, of course, have their most powerful supply of 'negative entropy' in the sunlight.)" (pp. 73-73)
from Erwin Schrodinger's "What is life?"
Entropy defined
"What is entropy? Let me first emphasize that it is not a hazy concept or idea, by a measurable physical quantity just like the length of a rod, the temperature at any given point of a body, the heat of fusion of a given crystal or the specific heat of any given substance. At the absolute zero point of temperature (roughly - 273°C) the entropy of any substance is zero. When you bring the substance into any other state by slow, reversible little steps (even if thereby the substance changes its physical or chemical nature or splits into two or more parts of different physical or chemical nature) the entropy increases by an amount which is computed by dividing every little portion of heat you had to supply in the procedure by the absolute temperature at which it was applied — and by summing up all the small contributions" (p. 71).
"Much more important for us here is the bearing on the statistical concept of order and disorder, a connection that was revealed by the investigations of Boltzmann and Gibbs in statistical physics. This too is an exact quantitative connection, and is expressed by
entropy = k log D,
where k is the so-called Boltzmann constant ( = 3.2983×10⁻²⁴ cal./°C) and D a quantitative measure of the atomistic disorder of the body in question. To give an exact explanation of this quantity D in brief non-technical terms is well-nigh impossible. The disorder it indicates is partly that of heat motion, party that which consists in different kinds of atoms or molecules being mixed at random, instead of being neatly separated ..." (p. 72).
