When you think of the tremendous technological progress we have made, it's amazing how little we have developed in other respects. We may speak scornfully of the poor old Romans because they enjoyed the seemingly excited killing that went on in their arenas . We may despise them because they mistook these goings on for entertainment. We may forgive them because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don't the audience who attend them hope they will see some violence? Human beings remain as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungry lions tearing people apart and eating them alive, we find all sorts of arguments to defend sports which should have been banned long ago. It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men punch each other in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Any talk of 'the sporting spirit' is merely hypocrisy . People take part in violent sports because of the high rewards they bring. Audience are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they haven't experienced the exquisite pleasure of witnessing continuous violence. Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally--though with little success. But at least we no longer tolerate the sight madmen imprisoned in cages, or public punishment of any of the countless other barbarous   practices which were common in the past. Prisons are no longer the harsh forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is unworthy of human beings. How many dangerous sports does the author mention in this passage?
