Our legal systems, our religions, our educational systems are all deeply concerned with controlling pleasure. We have created detailed rules and customs surrounding sex, drugs, food, alcohol, and even gambling. Jails are bursting with people who have violated laws that proscribe certain forms of pleasure or who profit by encouraging others to do so.

Most experiences in our lives that we find transcendent - whether illicit vices or socially sanctioned ritual and social practices as diverse as exercise, meditative prayer, dancing 'til you drop, and playing on the internet: They all evoke neural signals that converge on a small group of interconnected brain areas called the medial forebrain pleasure circuit. Evolution has, in effect, hardwired us to catch a pleasure buzz from a wide variety of experiences from crack to cannabis, from meditation to masturbation, from Bordeau to beef. 

 

Physiologists have long been in the habit of studying not the reactions of the whole organism but the reactions of isolated segments; the so-called reflexes. While it may seem justifiable to construct the reactions of the organism as a whole from the individual reflexes, such an attempt is in reality doomed to failure, since the reactions produced in an isolated element cannot be counted upon to occur when the same element is part of the whole, on account of the mutual inhibitions which the different parts of the organism produce upon each other when in organic connection; and it is, therefore, impossible to express the conduct of a whole animal as the algebraic sum of the reflexes of its isolated segments.... It would, therefore, be a misconception to speak of tropism as of reflexes, since tropisms are reactions of the organism as a whole, while reflexes are reactions of isolated segments. Reflexes and tropisms agree, however, in one respect, inasmuch as both are obviously of a purely physico-chemical character.

The time-binding capacity or energy of man (no matter what time is—if it is), which is unique to man, is a most subtle complex; it is the highest known energy and probably has many subdivisions. Ears are sensitive to the vibration of the air. Eyes are sensitive to the more subtle vibrations of light; in a similar way, the time-binding apparatus is sensitive to the most subtle energies; besides which it has the capacity to register not only all of our sensations but also the time-binding energies of other people; and it apparently has the capacity to register the energies of the universe.
