“If you were part of a group there was always the chance that the predator would take the next guy, not you. It was a cold-blooded lottery that paid off often enough to be worthwhile adapting for.
But there were disadvantages to group living: mainly, if there were large numbers of you, there was increased competition for food. As that competition resolved itself, the inevitable result was social complexity—and the size of the adapids’ brains had increased so that they were capable of handling that complexity. Then, of course, they were forced to become even more efficient at searching for food to fuel those big brains.
It was the way of the future. As primate societies became ever more complex, a kind of cognitive arms race would continue, increasing smartness fueled by increasing social complications.”

A Battle For Life (July 1958)
Context: This was a good beginning. All the outmoded rules of the hospital were broken. Minds which had been tied down by subservience to foreign experience were now set in motion. People began to speak, to think and to act boldly. A new world opened in front of them. They knew that what they were doing now was something unprecedented which doctors in capitalist countries had not been able to do. They were engaged in a battle to save lives and as the scope of the battle became wider an increasing number of people were drawn in. Later on when a difficulty occurred in the course of treatment they solicited the opinions of many doctors both within and without the hospital, depending on the wisdom of the many to tide over one crisis after another.
