It was who said, "i dare to believe that when the human being is inwardly free to choose whatever he deeply values, he tends to value those objects, experiences, and goals that will make for his own survival, growth, and development, and for the survival and development of others."

I believe the answer is: Carl rogers.

Carl rogers is regarded as the founder of humanistic approach of psychology.
He argued that All people have the capability to be 'good' ,

but the need for survival often took over and make humans tend to overlook the needs of other since we're most likely to prioritized our own survival

But if our own survival is guaranteed, we would be much more likely t turn around and help others in their survivial.
