... effort is a strife or a struggle to transform that which is into something which you wish it to be. I am only talking about psychological struggle, not the struggle with a physical problem like engineering or some discovery or transformation which is purely technical. I am talking only of that struggle which is psychological and which always overcomes the technical. You may build with great care a marvellous society, using the infinite knowledge science has given us. But as long as the psychological strife and struggle and battle are not understood, and the psychological overtones and currents are not overcome, the structure of society, however marvellously built is bound to crash, as has happened over and over again.
