Synonyms: Effect, Consequence, Result. These words indicate things which arise out of some antecedent, or follow as a consequent. Effect, which may be regarded as the generic term, denotes that which springs directly from something which can properly be termed a cause. A consequence is more remote, not being strictly caused, nor yet a mere sequence, but following out of and following indirectly, or in the train of events, something on which it truly depends. A result is still more remote and variable, like the rebound of an elastic body which falls in very different directions. We may foresee the effects of a measure, may conjecture its consequences, but can rarely discover its final results. "Resolving all events, with their effects And manifold results, into the will And arbitration wise of the Supreme." "Shun the bitter consequence, for know, The day thou eatest thereof,... thou shalt die."
