A man having little learning does much harm to him as well as to others. Sometimes he proves to be a danger to society. Such a man boasts of his learning. He talks and behaves in such a way that he knows much. But really learned men never make a show of their learning. They are modest. They know that though they have learned much.
But really learned men never make a show of their learning. They are modest. They know that though they have learned much, they have yet to learn much more. The truth of the saying is clearly shown in the case of a quack. He has got a little knowledge of medicine.
But he tries to prove that he is an efficient doctor. He is bold enough to treat diseases of which he knows very little. The result is that he makes the case worse and sometimes kills his patient. So a quack is a danger to society.
A machine with a little straining may also prove to be dangerous. He may handle machine, but he does not know how to work them well. The machine may be damaged. He may lose his own life even. So a man should always try to make an exact estimate of his worth. He should not pose to be what he is not really. By this he will do no good not only to society but also to himself.
