I have found that truly to accept another person and his feelings is by no means an easy thing, any more than is understanding. Can I really permit another person to feel hostile toward me? Can I accept his anger as a real and legitimate part of himself? Can I accept him when he views life and its problems in a way quite different from mine? Can I accept him when he feels very positively toward me, admiring me and wanting to model himself after me? All this is involved in acceptance, and it does not come easy.
I believe that it is an increasingly common pattern in our culture for each one of us to believe, “Every other person must feel and think and believe the same as I do.” We find it very hard to permit our children or our parents or our spouses to feel differently than we do about particular issues or problems. We cannot permit our clients or our students to differ from us or to utilize their experience in their own individual ways. On a national scale, we cannot permit another nation to think or feel differently than we do. Yet it has come to seem to me that this separateness of individuals, the right of each individual to utilize his experience in his own way and to discover his own meanings in it,—this is one of the most priceless potentialities of life. Each person is an island unto himself, in a very real sense; and he can only build bridges to other islands if he is first of all willing to be himself and permitted to be himself. So I find that when I can accept another person, which means specifically accepting the feelings and attitudes and beliefs that he has as a real and vital part of him, then I am assisting him to become a person: and there seems to me great value in this.
