Chiropractic is based on a law of biology that there is existent in the organism an ability to be stable, healthy, or to get well. Often called the law of homeostasis, it is stated as the ability to be well within it-self and within it's environment.
Chiropractic draws on the theory of physiology that the nervous system, consisting of the brain, spinal cord, cranial and spinal nerves, and the autonomic nervous system, and special sense organs such as the eye and ear, controls and coordinates all other organs and structures, and relates the organism to it's environment.
Chiropractic hypothesizes a relationship between the integrity or health in the nervous system, and integrity or health in the organism.
Chiropractic conjectures on the major premise that a disturbance of body framework can relate to a disturbance of the nervous system. These inter-relating disturbances are called the subluxation complex.
Law: A proven fact of science.
THEORY: The generally accepted viewpoint of science. Data tends towards proof, and none seriously challenges.
HYPOTHESIS: A statement made assumes as leading to a conclusion, and in a data-gathering mode. Sometimes called "the working tool of science."
CONJUNCTURE: Sometimes called premise, this is a statement made from qualification and preperation, as an opinion about events that have happened. An educated guess.
