ABSTRACT
Philosophy cannot be fruitful if divorced from empirical science. And by this I do not mean only that the philosopher should ‘get up’ some science as a holiday task. I mean something much more intimate: that his imagination should be impregnated with the scientific outlook and that he should feel that science has presented us with a new world, new concepts and new methods, not known in earlier times, but proved by experience to be fruitful where the older concepts and methods proved barren.
