Strona 128 - The kernel of the scientific outlook is the refusal to regard our own desires, tastes, and interests as affording a key to the understanding of the world.
Strona 162 - I often say that when you can measure what you are speaking about and express it in numbers you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.

Strona 142 - I am one of those who think that the methods of Science are not so limited in their scope as has been thought : that they can be applied much more widely, and that the Psychic region can be studied and brought under law too. Allow us anyhow to make the attempt. Give us a fair field. Let those who prefer the materialistic hypothesis by all means develop their thesis as far as they can; but let us try what we can do in the Psychical region, and see which wins.
Strona 111 - As stated in the charter, it was intended "to give the highest specialized instruction and to provide the fullest equipment for the most advanced training and research in various branches of science, especially in its application to industry.

Strona 142 - ... necessity, and has left some evil effects. And one of them is this lack of sympathy, this occasional hostility, to other more spiritual forms of truth. We cannot really and seriously suppose that truth began to arrive on this planet a few centuries ago. The pre-scientific insight of genius — of poets and prophets and saints — was of supreme value, and the access of those inspired seers to the heart of the universe was profound.
Strona 140 - Live thou, and of the grain and husk, the grape And ivyberry, choose ; and still depart From death to death thro' life and life, and find Nearer and ever nearer Him who wrought Not Matter, nor the finite-infinite, But this main miracle, that thou art thou, With power on thine own act and on the world.
Strona 140 - But life itself — life and mind and consciousness — they are not studying, and they exclude them from their purview. Matter is what appeals to our senses here and now; Materialism is appropriate to the material world ; not as a philosophy but as a working creed, as a proximate and immediate formula for guiding research. Everything beyond that belongs to another region, and must be reached by other methods. To explain the Psychical in terms of Physics and Chemistry is simply impossible; hence...
