Entropy.
The best (most succinct and precise) definition (description) of entropy is as it occurs in the "Second Law of Thermodynamics"; "All ordered systems, left to themselves tend toward maximum randomness and lowest energy (potential or differential)". That means that order naturally tends to degenerate into randomness (disorder) and energy potential tends to dissipate into a uniformity without potential because there's there's nowhere of lower potential left to go to...
Because energy must be dissipated in the maintenance, or sustaining, of an orderly system some con men with an ideology to sell will try to pretend that the energy consumed in the process creates the order. A sly mental trick.
Let's propose some practical examples to illustrate the process.
Most mothers like to have an orderly home. Order in her home requires:
1. An intellect to conceive the order.
2. The will to want the order.
3. The capacity, or power, to implement, or bring about, the order.
Now, that poor Mum who has been toiling away for years to install and maintain the order suddenly finds herself confronted by a clever-dick progeny who's been to school and learned that energy spontaneously creates order. SmArty tries to convince Mum that letting off a bomb (great release of energy) in the middle of her expertly managed domain, will spontaneously create order and she'll never have to tidy up again. Good luck with that one Smarty.
Or let's lift great weights to great heights. An intellect comes up with an idea of a crane to do the job. Skilled minds and hands divert energy and materials to make the machine using entropy in every step of the process. Smarty, with the benefit of his recently aquired great insights, comes along and proclaims that because the energy to build and operate the crane comes, ultimately, from the Sun then the Sun built the crane. Now, I just happen to know for sure that Central Australia gets lots and lots of solar energy but not one giant crane has ever spontaneously appeared in the desert.
Oh well, counters Smarty, "that only applies to non-biological systems. Energy applied to biological systems creates an increase in order and complexity opposed to entropy". Smarty has never heard of the "Law of Morphology" (which is really only entropy applied to biological systems) which says, simply, that "the more complex an organism and the more often it is reproduced, the more likely it is that something will go wrong in the process".
So, the thousands of generations of Drosophilla (fruit flies) that have been subjected to every imaginable radiation "stimulus" to produce "sped up" "evolution" have only ever produced some wreckage of their DNA or genome... not one super-human spaceman.
Ultimately, untold thousands of generations of diligent and wise housekeeping Mums are in tune with reality... the Smartys are not.
Order is a product of Intellect, Will, and Life.
