Happiness in this world, when it comes, comes incidentally. Make it the object of pursuit, and it leads us a wild-goose chase, and is never attained. Follow some other object, and very possibly we may find that we have caught happiness without dreaming of it. – Nathaniel Hawthorne
Natural science will in time incorporate into itself the science of man, just as the science of man will incorporate into itself natural science: there will be one science. – Karl Marx
