为了诱导人们实行兼爱,所以墨子在上述的道理之外,又引进丁许多宗教的、政治的制裁。因此,《墨子》有几篇讲“天志”,“明鬼”。其中说,天帝存在,天帝爱人,天帝的意志是一切人要彼此相爱。天帝经常监察人的行动,特别是统治者的行动。他以祸惩罚那些违反天意的人,以福奖赏那些顺从天意的人。除了天帝,还有许多小一些的鬼神,他们也同天帝一样,奖赏那些实行兼爱的人,惩罚那些交相“别”的人。
有一个墨子的故事与此有关,很有趣味。故事说:“子墨子有疾。跌鼻进而问曰;先生以鬼神为明,能为祸福,为善者赏之,为不善者罚之。今先生圣人也,何故有疾?意者先生之言有不善乎?鬼神不明知乎?子墨子曰;虽使我有病,鬼神何遽不明?人之所得于病者多方:有得之寒暑,有得之劳苦。百门而闭一门焉、则盗何遽无从人?”(《墨子·公孟》)如果用现代逻辑的术语,墨子可以说,鬼神的惩罚是一个人有病的充足原因,而不是必要原因。
In order, therefore, to induce people to practice the principle of
all-embracing love, Mo Tzu, in addition to the foregoing arguments,
Iintroduces a number of religious and political sanctions. Thus in the
Me-t:w there are chapters on "The Will of Heaven," and also oncs
titled "Proof of the Existence of Spirits." In these we read that God
I~exists; that He loves mankind; and that His Will is that all men
should love one another. He constantly supervises the activities of
~en, especially those of the rulers of men. He punishes with calamities persons who disobey His Will, and rewards with good fortune
those who obey. Besides God, there are also numerous lesser spirits
j who likewise reward men who practice all-embracing love, and punish
those who practice "discrimination."
In this connection there is an interesting story about Mo Tzu:
"When Mo Tzu was once ill, Tieh Pi came to him and inquired:
I 'Sir, you hold that the spirits are intelligent and control calamities
and blessings. They reward the good and punish the evil. Now you
are a sage. How then can you be ill? Is it that your teaching is not
I" entirely correct or that the spirits are after all not intelligent?' Mo
Tzu replied: 'Though I am ill, why should the spirits be unintelli-
,gent? There are many ways by which a man can contract diseases.
Some are contracted from cold or heat, some from fatigue. If there
,are a hundred doors and only one be closed, will there not be ways
by which robbers can enter?''' (Mo-tw, eh. 48.) In modern logical
,terminology, Mo Tzu would say that punishment by the spirits is a
sufficient cause for the disease of a man, but not its necessary cause.
