马克思说：“搬运夫和哲学家之间的原始差别要比家犬和猎犬之间的差别小得多。他们之间的鸿沟是分工掘成的。”

There is almost no origional difference between a manual labor worker and a philosopher. Both of them are humen, they have the same natural nature that all living creatures have in this world. They have to eat, drink and sleep in order to survive. They both have the basic social nature that distinguises them from animals, they work to make livings and enjoy life.

The reason said by Marx which causes the huge gap between a manual labor worker and a philosopher is the division of labor. In simple words, the work that they each do to make livings makes the differences. The essencial difference between one human and another human lies in what you do after you were born into this world---people's soicial nature differences.

As against the famous saying in the "Declaration of Independence", there is an old chinese saying which i forget said by who going like this "each one were born uneaqual"(人生自不齐). It talks about the origional differences between human beings. Some people were born to be genius, some others were born disable. Some people were born in a rich family which could afford them to go to the best university in the world, some others were born in barren villages where no one knows what school is. This also makes differences.
