==Etymology==The terms "actus reus" and "mens rea" developed in English Law are derived from the principle stated by Edward Coke, namely, "actus non facit reum nisi mens sit rea", which means: "an act does not make a person guilty unless (their) mind is also guilty"; hence, the general test of guilt is one that requires proof of fault, culpability or blameworthiness both in thought and action.
