10 Mar causal relation

One method of defining knowledge is to represent cause and effect as related entities. A causal relation links causes to effects in an understandable way, such as is done in a logical theorem (e.g. if it rains, then plants will grow). The relation between a cause and its effect or between regularly correlated events or phenomena may be intentional (or the result of some organisms intended action) or natural (some event in the physical universe that follows the normal course of the interaction of particles and objects). See Causal Chains in Action.
