“If the inner psychic ground of our individual appearance were not always the same, there could be no science of psychology, which qua science relies on a psychic “inside we are all alike,” just as the science of physiology and medicine relies on the sameness of our inner organs. […] The monstrous sameness and pervasive ugliness so highly characteristic of the findings of modern psychology, and contrasting so obviously with the enormous variety and richness of overt human conduct, witness to the radical difference between the inside and the outside of the human body.”

Evolution and Ethics (1893)
Context: The history of civilization details the steps by which men have succeeded in building up an artificial world within the cosmos. Fragile reed as he may be, man, as Pascal says, is a thinking reed: there lies within him a fund of energy, operating intelligently and so far akin to that which pervades the universe, that it is competent to influence and modify the cosmic process. In virtue of his intelligence the dwarf bends the Titan to his will. In every family, in every polity that has been established, the cosmic process in man has been restrained and otherwise modified by law and custom; in surrounding nature, it has been similarly influenced by the art of the shepherd, the agriculturist, the artisan. As civilization has advanced, so has the extent of this interference increased; until the organized and highly developed sciences and arts of the present day have endowed man with a command over the course of non-human nature greater than that once attributed to the magicians.... a right comprehension of the process of life and of the means of influencing its manifestations is only just dawning upon us. We do not yet see our way beyond generalities; and we are befogged by the obtrusion of false analogies and crude anticipations. But Astronomy, Physics, Chemistry, have all had to pass through similar phases, before they reached the stage at which their influence became an important factor in human affairs. Physiology, Psychology, Ethics, Political Science, must submit to the same ordeal. Yet it seems to me irrational to doubt that, at no distant period, they will work as great a revolution in the sphere of practice.<!--pp.83-84

Context: Our aim is to sketch the outlines of a new science which is to intermediate between the modern laboratory psychology and the problems of economics: the psychological experiment is systematically to be placed at the service of commerce and industry. So far we have only scattered beginnings of the new doctrine, only tentative efforts and disconnected attempts which have started, sometimes in economic, and sometimes in psychological, quarters. The time when an exact psychology of business life will be presented as a closed and perfected system lies very far distant. But the earlier the attention of wider circles is directed to its beginnings and to the importance and bearings of its tasks, the quicker and the more sound will be the development of this young science. What is most needed to-day at the beginning of the new movement are clear, concrete illustrations which demonstrate the possibilities of the new method. In the following pages, accordingly, it will be my aim to analyze the results of experiments which have actually been carried out, experiments belonging to many different spheres of economic life. But these detached experiments ought always at least to point to a connected whole; the single experiments will, therefore, always need a general discussion of the principles as a background. In the interest of such a wider perspective we may at first enter into some preparatory questions of theory. They may serve as an introduction which is to lead us to the actual economic life and the present achievements of experimental psychology

Context: I cannot experience your experience. You cannot experience my experience. We are both invisible men. All men are invisible to one another. Experience used to be called The Soul. Experience as invisibility of man to man is at the same time more evident than anything. Only experience is evident. Experience is the only evidence. Psychology is the logos of experience. Psychology is the structure of the evidence, and hence psychology is the science of sciences.

Context: In our own inner selves, we find operating the same trio—ignorance, indifference, and carelessness. We are ignorant of our own latent capacities, of the degree of our likeness to God, of the possibilities of our lives. We are indifferent to the higher values and are content to the lower level of physical appetites and pleasures. Even when we recognize to some extent our possibilities and when we seek after a fashion to realize them, we grow careless, become swamped by the temporary, and lose sight of the eternal.... A lack of appreciation of the intrinsic worth and latent possibilities of every man we meet, indifference to his welfare, and carelessness as to his rights and privileges, prevent us from living on friendly terms with him.
