The sixth sense can also be called extrasensory perception, which is known as ESP. It means knowing sth.without using any of the five senses---seeing, hearing, smelling, tasting and touching. The first example of the sixth sense given by the author concerns mothers. A mother is sometimes able to predict the dangers which will fall upon her children, and protect them from being injured.

The second example is of a famous escape artist. He was saved from drowning by following the voice of his mother who lived far away. Even more amazing is that when he was out of the icy water and tried to telephone his mother, he was informed that she had died that day. Then, what is mother’s intuition? We still do not know. Maybe it is the intimate relationship between mother and child that inspires sth. mysterious in the mother, which urges her to help her child. This mysterious thing is what we call the sixth sense. Someday, the sixth sense may be explained logically.
