Our striving is a combat, or a struggle, in order to transform what you are to something you wish to be.
I speak exclusively about the philosophical struggle, where you seek to produce yourself, the struggle of meaning, not about the struggle, which has to be led with a physical problem, as for instance an engineering project, or a discovery, or a change, which is of purely technical kind. I only talk about the philosophical struggle, which always overshadow the technical.
You can with the utmost care - as you draw advantage of the limitless knowledge which science has granted us - build a wonderful society. But as long as you don't understand those philosophical sticking points, the philosophical struggle which is going on - as long as these philosophical overtones and streams not are being solved - the structure of society must, how wonderful and solid it might be, necessarily be crushed, in the way it, through history, again and again has happened.
