It sounds good externally, but in reality it isn't good. We can never develop our heart with such an attitude. Heart and intellect both need truth in order to develop properly. The desert is a good example to illustrate the relationship between heart and intellect. Just as this world becomes a desert when there is no water, our character becomes a desert if we have no heart.
Heart is the water of life.
Too much water can cause floods though. So God created emotion and intellect to interact in harmony and control each other. All things need some form of control. For example, no matter how rich you are, if you don't control how your money is spent, it will soon be gone. And if we don't control our physical body, it will quickly wear out or get sick.
