Love is a wondrous state, deep, tender, and rewarding.Because of its intimate and personal nature, it is regarded by some as an improper topic for experimental research.But, whatever our personal feelings may be, our assigned mission as psychologists is to analyze all facets (方面) of human and animal behavior into their component variables. So far as love or affection is concerned, psychologists have failed in this mission. The little we know about love does not transcend simple observation, and the little we write about it has been written better by poets and novelists.But of greater concern is the fact that psychologists tend to give progressively less attention to a motive which pervades our entire lives. Psychologists, at least psychologists who write textbooks, not only show no interest in the origin and development of love or affection, but they seem to be unaware of its very existence.

The apparent repression of love by modern psychologists stands in sharp contrast with the attitude taken by many famous and normal people. The word "love" has the highest reference frequency of any word cited inBartlett’s Book of Familiar Quotations. It would appear that this emotion has long had a vast interest and fascination for human beings, regardless of the attitude taken by psychologists; but the quotations cited, even by famous and normal people, have a mundane redundancy. These authors and authorities have stolen love from the child and infant and made it the exclusive property of the adolescent and adult.
The best statement of the main idea for the passage is ______.
A、Bartlett’s book publishes quotations about love
B、love is a wondrous state, deep, tender and rewarding
C、psychologists write terrible textbooks because they ignore love
D、psychologist must study all aspects of human behavior, including love
