“The remaining books of the Laws, ix-xii, are chiefly concerned with criminal offences. In the first class are placed offences against the Gods, especially sacrilege or robbery of temples: next follow offences against the state,—conspiracy, treason, theft. The mention of thefts suggests a distinction between voluntary and involuntary, curable and incurable offences. Proceeding to the greater crime of homicide, Plato distinguishes between mere homicide, manslaughter, which is partly voluntary and partly involuntary, and murder, which arises from avarice, ambition, fear. He also enumerates murders by kindred, murders by slaves, wounds with or without intent to kill, wounds inflicted in anger, crimes of or against slaves, insults to parents. To these, various modes of purification or degrees of punishment are assigned, and the terrors of another world are also invoked against them.”
