The Theory

Roger’s theory is a clinical one, based on years of experience dealing with his clients. He has this in common with Freud, for example. Also in common with Freud is that his is a particularly rich and mature theory -- well thought-out and logically tight, with broad application.
Not in common with Freud, however, is the fact that Rogers sees people as basically good or healthy -- or at very least, not bad or ill. In other words, he sees mental health as the normal progression of life, and he sees mental illness, criminality, and other human problems, as distortions of that natural tendency. Also not in common with Freud is the fact that Rogers’ theory is a relatively simple one.
Also not in common with Freud is that Rogers’ theory is particularly simple -- elegant even! The entire theory is built on a single “force of life” he calls the actualizing tendency. It can be defined as the built-in motivation present in every life-form to develop its potentials to the fullest extent possible. We’re not just talking about survival: Rogers believes that all creatures strive to make the very best of their existence. If they fail to do so, it is not for a lack of desire.
Rogers captures with this single great need or motive all the other motives that other theorists talk about. He asks us, why do we want air and water and food? Why do we seek safety, love, and a sense of competence? Why, indeed, do we seek to discover new medicines, invent new power sources, or create new works of art? Because, he answers, it is in our nature as living things to do the very best we can!
Keep in mind that, unlike Maslow’s use of the term, Rogers applies it to all living creatures. Some of his earliest examples, in fact, include seaweed and mushrooms! Think about it: Doesn’t it sometimes amaze you the way weeds will grow through the sidewalk, or saplings crack boulders, or animals survive desert conditions or the frozen north?
He also applied the idea to ecosystems, saying that an ecosystem such as a forest, with all its complexity, has a much greater actualization potential than a simple ecosystem such as a corn field. If one bug were to become extinct in a forest, there are likely to be other creatures that will adapt to fill the gap; On the other hand, one bout of “corn blight” or some such disaster, and you have a dust bowl. The same for us as individuals: If we live as we should, we will become increasingly complex, like the forest, and thereby remain flexible in the face of life’s little -- and big -- disasters.
People, however, in the course of actualizing their potentials, created society and culture. In and of itself, that’s not a problem: We are a social creature, it is our nature. But when we created culture, it developed a life of its own. Rather than remaining close to other aspects of our natures, culture can become a force in its own right. And even if, in the long run, a culture that interferes with our actualization dies out, we, in all likelihood, will die with it.
Don’t misunderstand: Culture and society are not intrinsically evil! It’s more along the lines of the birds of paradise found in Papua-New Guinea. The colorful and dramatic plumage of the males apparently distract predators from females and the young. Natural selection has led these birds towards more and more elaborate tail feathers, until in some species the male can no longer get off the ground. At that point, being colorful doesn’t do the male -- or the species -- much good! In the same way, our elaborate societies, complex cultures, incredible technologies, for all that they have helped us to survive and prosper, may at the same time serve to harm us, and possibly even destroy us.
