A metaphysician is one who believes it when toxins from a dilapidated liver makes his brain whisper that mind is the boss of liver.

Even the humblest creature has to know how to react to the difference between food and toxin if it's to survive. ... Life and some level of intelligent behavior—discerning and doing what's best for one's survival—appear to go hand in hand.

Our contemporary culture, primed by population growth and driven by technology, has created problems of environmental degradation that directly affect all of our senses: noise, odors and toxins which bring physical pain and suffering, and ugliness, barrenness, and homogeneity of experience which bring emotional and psychological suffering and emptiness. In short, we are jeopardizing our human qualities by pursuing technology as an end rather than a means. Too often we have failed to ask two necessary questions: First, what human purpose will a given technology or development serve? Second, what human and environmental effects will it have?

The Industrial Revolution as a whole was not designed. It took shape gradually as industrialists and engineers figured out how to make things. The result is that we put billions of pounds of toxic materials in the air, water and soil every year and generate gigantic amounts of waste. If our goal is to destroy the world—to produce global warming and toxicity and endocrine disruption—we're doing great.

The organism possesses certain contrivances by means of which the immunity reaction, so easily produced by all kinds of cells, is prevented from acting against the organism’s own elements and so giving rise to auto toxins … so that one might be justified in speaking of a “horror autotoxicus” of the organism. These contrivances are naturally of the highest importance for the existence of the individual.

The specific character of the greater part of the toxins which are known to us (I need only instance such toxins as those of tetanus and diphtheria) would suggest that the substances produced for effecting the correlation of organs within the body, through the intermediation of the blood stream, might also belong to this class, since here also specificity of action must be a distinguishing characteristic. These chemical messengers, however, or 'hormones' (from όρμάω, I excite or arouse), as we might call them, have to be carried from the organ where they are produced to the organ which they affect by means of the blood stream and the continually recurring physiological needs of the organism must determine their repeated production and circulation through the body.

There is no sharp boundary line separating the reactions of the immune bodies from chemical processes between crystalloids, just as in nature there exists every stage between crystalloid and colloid. The nearer the colloid particle approximates to the normal electrolyte, the nearer its compounds must obviously come to conforming to the law of simple stoichiometric proportions, and the compounds themselves to simple chemical compounds. At this point, it should be recalled that Arrhenius has shown that the quantitative relationship between toxin and antitoxin is very similar to that between acid and base.

What we call recycling is typically the product losing its quality. Paper gets mixed with other papers, re-chlorinated and contaminated with toxic inks. The fiber length gets shorter…and you end up with gray, fuzzy stuff that doesn't really work for you. That's downcycling. Michael Braungart and I coined the term upcycling, meaning that the product could actually get better as it comes through the system.
