laws of thought

certain principles of logic, such as the identity principle, that are deemed to be so essential to rational thought as to assume the character of law. Indeed, such principles define the very idea of logical thought. Which logical principles should be included in a set of such laws is, however, a matter of debate.

syphilis

syphilis

n. a contagious disease caused by infection with the spirochete bacterium Treponema pallidum. Syphilis is usually a sexually transmitted disease, but it can be transmitted through a break or cut in the skin or mucous membrane; it can also be transmitted by an infected pregnant woman to an unborn child. Untreated, syphilis progressively destroys body tissues, particularly those of the heart and nervous system. See also cerebral syphilis; general paresis.
