A scientist is apt to think that all the problems of philosophy will ultimately be solved by science. I think this is true for a great many of the questions on which philosophers still argue. For example, Plato thought that when we saw something, one ray of light came to it from the sun, and another from our eyes and that seeing was something like feeling with a stick. We now know that the light comes from the sun, and is reflected into our eyes. We don' t know in much detail how the changes in our eyes give rise to sensation. But there is every reason to think that as we learn more about the physiology of the brain, we shall do so, and that the great philosophical problems about knowledge are going to be pretty fully cleared up.
But if our descendants know the answers to these questions and others that perplex ns today, there will still be one field of which they do not know, namely the future. However exact our science, we cannot know it ns we know the past. Philosophy may be described as argument about things of which we are ignorant. And where science gives us a hope of knowledge it is often reasonable to suspend judgment. That is one reason why Marx and Engels quite rightly wrote to many philosophical problems that interested their contemporaries.
But we have got to prepare for the future, and we cannot do so rationally without some philosophy. Some people say we have only got to do the duties revealed in the past and laid down by religion, and god will look after the future. Other say that the world is a machine and the course of future events is certain, whatever efforts we may make. Marxists say that the future depends on ourselves, even though we are part of the historical process. This philosophical view certainly does inspire people to very great achievements. Whether it is true or not, it is powerful guide to action.
We need a philosophy, then, to help us to tackle the future. Agnosticism easily becomes an excuse for laziness and conservatism. Whether we adopt Marxism or any other philosophy, we cannot understand it with-out knowing something of how it developed. That is why knowledge of the history of philosophy is important to Marxists, even during the present critical days.

听力原文： President Bush is sending over 20,000 more U.S. troops into Iraq. In an address from the White House last night, Mr. Bush said he considered suggestions from U. S. lawmakers to scale back U. S. efforts in Iraq. But he warned that stepping back now would force a collapse of the Iraqi government.
The consequences of failure are clear. Radical Islamic extremists would grow in strength and gain new recruits. They would be in a better position to topple moderate governments, create chaos in the region, and use oil revenues to fund their ambitions. Iran would be emboldened in its pursuit of nuclear weapons. Our enemies would have a safe haven from which to plan and launch attacks on the American people.
But Democratic Senator Richard Durbin says the president's new plan runs contrary to what his own generals have advised him to do.
General John Abizaid until recently, the commanding general in Iraq and Afghanistan, said, "More American forces prevent the Iraqis from doing more, from taking more responsibility for their own future."
And Republican Senator Sam Brownback on a visit to Iraq said he does not believe Sending more troops to Iraq is the answer.
