Redemption thus ceases to be the arbitrary whim of a deity; it ceases, in effect, to be exclusively transcendental and becomes anthropological. History imparts to faith a logic and intelligibility that inspires hope, meaning, and action. Augustine’s view of redemption is prospective rather than retrospective; the „golden age” of the pagan now lies in a historically conditioned future, one that is to be attained in a battle with evil, rather than a long-lost natural past. In Augustine’s time, this vision served to diffuse the millenarian hopes of the emerging Christian world for an imminent Second Coming of Christ. But it later haunted the Church like a postponed debt, whose claims must be honored by its clerical creditors sooner or later. The new code that was now to supplant valor and coercion also had a very old pedigree, notably in a reciprocity that had become standardized and lost its „accidental form” (to use Marx’s terminology) as a mode of exchange; indeed, one that was built on a clear and codifiable notion of equivalents.
Whatever their shortcomings as a substitute for wisdom and a world outlook, conventional logical operations are needed for survival. Women gathered plants, men shaped hunting implements, and children contrived games according to logical procedures that were closely akin to our own. We must not get caught up in direct comparisons between plants, animals, and human beings or between plant-animal ecosystems and human communities. We would be regressing in our views to those of Park, Burgess, and MacKenzie, not to mention our current bouquet of sociobiologists, were we lax enough to make this equation. It is not in the particulars of differentiation that plant-animal communities are ecologically united with human communities but rather in their logic of differentiation. The dynamic stability of the whole derives from a visible level of completeness in human communities as in climax ecosystems.

Relative time is the physical subdivision of the rocks found in the Earth’s geology and the time and order of events they represent. Absolute time is the measurement taken from the same rocks to determine the amount of time that has expired. Absolute time measurements can therefore be used to calibrate the relative time scale, producing an integrated geologic grizzly or „geochronologic” time scale that combines both types of data, as is depicted here. From the results of studies on the origins of the various kinds of rocks (petrology), coupled with studies of rock layering (stratigraphy) and the evolution of life (paleontology), today geologists reconstruct the sequence of events that has shaped the Earth’s surface.
Fossil species that are used to distinguish one layer from another are called index fossils. Usually index fossils are fossil organisms that are common, easily identified, and found across a large area. Organisms like pigs and rodents are more typically used because they are more common, widely distributed, and evolve relatively rapidly. Despite seeming like a relatively stable place, the Earth’s surface has changed dramatically over the past 4.6 billion years.
The wish to make this commitment haunts their entire work on reason and enlightenment, but it is a wish they were too prudent to satisfy. Perhaps less obviously, the same ambiguities also becloud our attitudes toward reason and science. To Enlightenment thinkers two centuries ago, reason and science (as embodied in mathematics and Newtonian physics) were latent with the hope of a human mind freed of superstition and of a nature freed of scholastic metaphysics. To put the issue quite directly, the „how” of things is inadequate unless it can be illuminated by the „why.” Events that lack the coherence of ethical meaning are merely random. They are alien not only to science but also to nature, for even more than the proverbial „vacuum,” nature abhors the incoherence of disorganization, the lack of meaning that comes with disorder. And it is hardly demeaning for science, in reconsidering its metaphysical presuppositions, to make room for other metaphysical presuppositions that can illuminate areas of subjectivity to which a strictly scientistic outlook has proven to be blind.
Lines of Evidence: The Science of Evolution
Radioactive isotopes of elements that are common in mineral crystals are useful for radioisotopic dating. The uranium/lead method, with its two cross-checking clocks, is most often used with crystals of the mineral zircon (ZrSiO4) where uranium can substitute for zirconium in the crystal lattice. Zircon is resistant to weathering which makes it useful for dating geological events in ancient rocks. During metamorphic events, zircon crystals may form multiple crystal layers, with each layer recording the isotopic age of an event, thus tracing the progress of the several metamorphic events [16].
It also created the issues that were to beleaguer the western mind and praxis for centuries to come — and a thoroughly repressive mentality for dealing with them. For better or worse, we are in no sense free of this legacy’s worldliness, candor, and logic. Cross-fertilized with Hebrew thought, European intellectuality was born in classical Athens and wound its way through the centuries until, like it or not, we still remain its heirs.

For some three centuries now, a scientific vision of reality has been solidly structured around the presupposition that we can interpret reality’s orderliness in the form of a scientific logic, rigorously answerable to such rationally demanding systems as mathematics. But no assumption or even suggestion has been made that logic and reason inheres in the world itself. It has presupposed, with astonishing success, that nature is orderly, and that this order lends itself to rational interpretation by the human mind, but that reason is exclusively the subjective attribute of the human observer, not of the phenomena observed. Ultimately, science has lived this lie primarily to avoid the most unavoidable „pitfalls” of metaphysics — that an orderly world that is also rational may be regarded as a meaningful world. Such a view implied that the very „imagination” in which the „architect raises his structure” is socially and ethically derivative. Perceived reality involves an epistemology of domination — or liberation — that cannot be reduced to technical grounds alone.
The records are too dim to give us a clear idea of all the issues that may have produced internal conflicts within Sumerian cities, but a leap from tribalism to despotism is obvious myth. The threat of an emergency was never absent once the cities flourished and increased in number. Contiguous fields, questions of drainage and irrigation, the safe-guarding of supplies by procuring safety in transit — all these might become matters of dispute between neighboring cities. We can follow through five or six generations a futile and destructive war between Umma and Lagash with a few fields of arable land as the stakes. For Aristotle, the threat of the unlimited lies not only in imbalance and dependence; it also lies in the subversion of form — without which identity itself dissolves and the meaningful is supplanted by the meaningless. Accordingly, Piaget finds that language, reflective thought, and the organization of a spatial, causal, and temporal universe become possible „to the extent that the self is freed of itself by finding itself and so assigns itself a place as a thing among things, an event among events.”
Despite all the accolades The Republic was to receive over the centuries after it was composed, it is not a utopia, a vision of a communist society, or in any sense of the term a democracy. What must be emphasized, here, is that Plato’s rationality is ruthlessly, even cynically or playfully, hierarchical. The polis, if it was to survive from Plato’s viewpoint, had to yield to the „cruelty of reason,” so to speak, and follow the full logic of domination. The Greeks — and they alone are of concern to Plato — must drastically alter the polis along the lines dictated by a repressive epistemology. Had reason, with its capacity for calculation, been used to divide and destroy rather than unite and create, the very human quality of humanity would have turned upon itself and the species immolated itself ages ago, long before it devised its armamentarium of modern weaponry. These limitations acquire an almost stark character in the European centricity of his sense of history, particularly as revealed in his emphasis on the „progressive role of capitalism” and his harsh metaphors for the noncapitalist world.
Nonconformity, where sedimentary strata are deposited on crystalline (igneous or metamorphic) rocks. Just as the magnetic needle in a compass will point toward magnetic north, small magnetic minerals that occur naturally in rocks point toward magnetic north, approximately parallel to the Earth’s magnetic field. Because of this, magnetic minerals in rocks are excellent recorders of the orientation, or polarity, of the Earth’s magnetic field.
