antiseptic,

agent that kills or inhibits the growth of microorganisms on the external surfaces of the body. Antiseptics should generally be distinguished from drugs such as antibiotics that destroy microorganisms internally, and from disinfectants, which destroy microorganisms found on nonliving objects. Germicides include only those antiseptics that kill microorganisms. Some common antiseptics are alcohol, iodine, hydrogen peroxide, and boric acid. There is great variation in the ability of antiseptics to destroy microorganisms and in their effect on living tissue. For example, mercuric chloride is a powerful antiseptic, but it irritates delicate tissue. In contrast, silver nitrate kills fewer germs but can be used on the delicate tissues of the eyes and throat. There is also a great difference in the time required for different antiseptics to work. Iodine, one of the fastest-working antiseptics, kills bacteria within 30 sec. Other antiseptics have slower, more residual action. Since so much variability exists, systems have been devised for measuring the action of an antiseptic against certain standards. The bacteriostatic action of an antiseptic compared to that of phenol (under the same conditions and against the same microorganism) is known as its phenol coefficient. Joseph Lister was the first to employ the antiseptic phenol, or carbolic acid, in surgery, following the discovery by Louis Pasteur that microorganisms are the cause of infections. Modern surgical techniques for avoiding infection are founded on asepsis, the absence of pathogenic organisms. Sterilization is the chief means of achieving asepsis.

One way of defining our real, absolutely fundamental problem -- the one that makes it impossible to leave each other alone or ignore each other, but that also makes it exceedingly difficult for us to live with and accept each other -- is, to put it somewhat antiseptically, that we are two quite different communities of interpretation of a single tradition, out of which we have shaped our different identities.

However this theory, which is incorrectly seen by some as having replaced development economics, does no better than reinvent the wheel which then gets stuck in its trained incapacity to handle problems of economic development for the simple reason that it is antiseptically neo-classical: it makes extremely stringent assumptions about international production functions as it assumes a single sector, or that all sectors are symmetrical in nature.
