Of the Means of preventing Crimes.
It is better to prevent crimes than to punish them. This is the fundamental principle of good legislation, which is the art of conducting men to the maximum of happiness, and to the minimum of misery, if we may apply this mathematical expression to the good and evil of life. But the means hitherto employed for that purpose are generally inadequate, or contrary to the end proposed. It is impossible to reduce the tumultuous activity of mankind to absolute regularity; for, amidst the various and opposite attractions of pleasure and pain, human laws are not sufficient entirely to prevent disorders in society. Such, however is the chimera of weak men, when invested with authority. To prohibit a number of indifferent actions is not to prevent the crimes which they may produce, but to create new ones, it is to change at will the ideas of virtue and vice, which, at other times, we are told, are eternal and immutable. To what a situation should we be reduced if every thing were to be forbidden that might possibly lead to,a crime? We must be deprived of the use of our senses: for one motive that induces a man to commit a real crime, there are a thousand which excitehim to those indifferent actions which are called crimes by bad laws. If then the probability that a crime will be committed be in proportion to the number of motives, to extend the sphere of crimes will be to increase that probability. The generality of laws are only exclusive privileges,the tribute of all to the advantages of a few.


it is known to all that crime rate is on the rise. the means of committing a crime is numerous and varied. murder and robbery, not to speak of theft, are often seen. what causes crime rate to rise? i think the reasons are as follows:
　　first, there exists the unfaisness in distribution. more work does not result in more pay. the tycoons are not hard-working people but profiteers. some government officials abuse power and make public money their own.second, the influence of violence and horror films on young people has a negative effect. the films and songs about love and revenge and friendship teach young people to give kiadness for kindness, hatred for hatred and tit for tat.third, people tend to lose faith and belief. the traditional revolutionaly education has somewhat been abandoned. people talk less about patriotism but more about making money. the money-oriented people are cold and indifferent to each other.
　　there are many social and economical reasons that cause crime rate to rise. the above mentioned are just a few. they are the dark side of human society. by the joint efforts of people both of rank and file we are sure to make a better world in which to live.
