Scientific fact

“ Man constructed a science of numbers, of the stars, of molar and molecular masses, of plants, of stones, and of creeping things, before he realized that he was himself an object capable of receiving scientific attention. ”

“ Seen in its subjective aspect, each of the steps in the growth of this adjustment is a recognition of a scientific law, the perception of the permanency of a relation between external phenomena; for science is simply the recognition of the order of nature. ”

“ In any special natural science, a scientific description appears as an adjustment, express, conscious, exact, of the internal structure of a system of ideas to the external structure of a world of preexistent facts; and the business of science has been repeatedly defined, of late years, as simply and wholly taken up with the exact description of the facts of nature. ”

“ Aims at a critical comparison of scientific methods of thought, with special reference to the relations between biology and the " exact sciences " of chemistry and physics.
"Interesting and valuable . . . original and striking . . . should be read and studied by all thinking men and women." — Education. ”

“ A person observing the occurrence of certain facts and phenomena asks, naturally enough, what process, what kind of operation known to occur in nature applied to the particular case, will unravel and explain the mystery? Hence you have the scientific hypothesis; and its value will be proportionate to the care and completeness with which its basis had been tested and verified. It is in these matters as in the commonest affairs of practical life: the guess of the fool will be folly, while the guess of the wise man will contain wisdom. ”

“ Modern science explains the changes of the natural world by the hypothesis of certain unconscious forces; and the sum of these forces, in their combined action, constitutes the scientific conception of nature. ”

“ I am not a practical chemist seeking the mysteries of nature in the laboratory, nor a professional scientist exploring the fields of original research; but, like La Place, Comte, Herbert Spencer and others, I formulate my theories and scientific hypotheses from the latest and best established facts of science as I see it. ”

“ The great results of the scientific investigation of nature we are agreed upon knowing, but how much of our study are we bound to give to the processes by which those results are reached? The results have their visible bearing on human life. ”

“ One of the urgent needs of modern physical science is a thorough investigation of the nature, methods, and aids of scientific cognition, and thus of the nature of its real limits, chiefly in the light of the teachings of comparative philology and comparative psychology. ”

“ If we choose to define positive science as the systematic establishment of the special laws of connection between facts, we may say that over and above the scientific problem of the systematisation of facts there is the further philosophical problem of their interpretation. ”

“ We see in many of the brute creation the exercise of one, at least, of the same powers of reasoning as that which we ourselves employ.
The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind. ”

“ Science being proved truth, scientific method requires that all the factors which concern the subject of research shall be duly considered, in order to arrive at correct thought respecting the special subject of inquiry. ”

“ Now that science has entered into her kingdom and the vastness of her domain is willingly recognized,—for in a vital sense all that may be known by human ken, supported by evidence, presented in orderly arrangement, related to other knowledge, and developed by further study may be called science,—the busy problem is the infusion of the scientific method into all our ways of thinking, its application to all the various kinds of beliefs that affect our ideals, our working conceptions, and our actions. ”

“ My success in your cause must be attributed to my having followed the path of experiment and induction discovered by philosophers who have preceded me: willingly would I divide your plaudits with other men of science, and claim much for the general glory of scientific discovery in a long course of ages. ”

“ But in the Nineteenth Century physical science re-discovered the truth and the Twentieth Century scientific discoveries have added additional proof of the correctness and truth of this centuries-old Hermetic doctrine. ”

“ But in each of those sciences we shall obtain solid and complete systems of knowledge, only so far as we study, with steady thought and careful observation, that peculiar kind of cause which is appropriate to the phenomena under our consideration. ”

“ The other consideration I have to put before you is that, whatever may be the results at which physical science as applied to man shall arrive, those results are inevitable—I mean that they arise out of the necessary progress of scientific thought as applied to man. ”

“ Whether we examine the course of the planets or the world of the animalculæ; to whatever field of physical nature our research is turned, the uniform, invariable result of scientific enquiry is to show that even the most apparently irregular and surprising phenomena are governed by natural antecedents, and are parts of one great connected system. ”

“ Science: the Knowledge of the Laws of Nature obtained by Observation, Experiment, and Reasoning. No line can be drawn between common knowledge of things and scientific knowledge; nor between common reasoning and scientific reasoning. In strictness all accurate knowledge is Science; and all exact reasoning is scientific reasoning. The method of observation and experiment by which such great results are obtained in science, is identically the same as that which is employed by every one, every day of his life, but refined and rendered precise. ”

“ For the latter half of the eighteenth century, when the foundations of our modern science were being rapidly laid, a considerable list might be given of early publications of similar scientific bodies. ”

“ We have dwelt long enough on these generalities, and it is time to come down to commonplaces, and to inquire what are the essential conditions of this scientific culture which shall fit us to investigate Nature; and the first thought that occurs to me in this connection may be expressed thus: Science presents to us two aspects, which I may call its objective and its subjective aspect. Objectively it is a body of facts, which we have to observe, and subjectively it is a body of truths, conclusions, or inferences, deduced from these facts ”

“ And when we fully recognize that a problem is being solved, we have only to gain some appreciation of its general nature and conditions, in order to reach some important, though limited, conclusions, which may fairly be called scientific, as to the meaning of the answer. These conclusions are not scientific in the sense of giving us quantitative and precise formulæ, but they may be so far scientific as to be certain and reliable. ”

“ It is a general truth that the physical sciences of light and heat are based upon mechanical conditions of the particles of matter; that the science of chemistry is founded upon physics; that biological phenomena are dependent upon physical and chemical conditions; that psychological subjects are based upon biology; and that biological science cannot progress excepting in proportion to the advance of the sciences on which it is based. ”

“ Secondly, the progress of the biological and psychological sciences, as I have already pointed out, has considerably altered the outlook of those who pin their faith to the newer or scientific view of nature, the view which attempts constantly to refer speculations to reality, and to build on foundations which have been tested by experiment. ”

“ But yet a progress of thought upon such subjects,—an advance from the obscure to the clear, and from errour to truth,—may be traced in the world at large, and among those who have not directly cultivated the exact sciences. ”

“ So, disregarding the opinions of certain cultivators of science, we are here to ask the more pertinent question, What is there — if indeed there be anything — in the nature of science itself, as science is now known, what is there in its results or in its method, that points to a pantheistic interpretation of the world? ”

“ The Trend of Scientific Investigations.—While research is carried on in many lines, with many different objectives, it may be stated that intense study is devoted to the nature of matter and the direct connection of it with elemental forces. ”

“ In so far as the chemical and biological sciences involve the recognition of qualitative distinctions and the consequent use of categories which are non-mechanical, it is these æsthetic and historical interests, and not the primary scientific interest in the control of natural phenomena, which are subserved by their elaboration. ”

“ Noted natural scientists, reflecting upon the principles of their science, have observed that the definitions of the concepts and the presuppositions of science must seek their justification in the fact that they furnish the possibility of an intellectual elaboration and interpretation of the facts. ”

“ These sciences are essentially sciences concerning organisms. During the epoch in question, and indeed also at the present moment, the prestige of the more perfect scientific form belongs to the physical sciences. ”

“ In science, as in art, and, as I believe, in every other sphere of human activity, there may be wisdom in a multitude of counsellors, but it is only in one or two of them. And, in scientific inquiry, at any rate, it is to that one or two that we must look for light and guidance. ”

“ The study of the exact sciences led you, against my will and your own, to a passion for the natural sciences, and, starting off at random, you thought of nothing but astronomy and of dreaming of worlds to which we can never go. ”

“ In examining, therefore, the truths which science has revealed to us, it is advantageous, for the purpose of fixing the mind to the subject, that we assume certain conditions as true. These may be stated in a few sentences, and then, without wasting a thought upon those metaphysical subtleties which have from time to time perplexed science, and served to impede the progress of truth, we shall proceed to examine our knowledge of the phenomena which constantly occur around us. ”

“ At first sight, it may seem prudent to leave the consideration of facts to positive science, to let physics and chemistry busy themselves with matter, the biological and psychological sciences with life. ”

“ We must here therefore be considerably involved in questions affecting theories which have gained wide favor in scientific circles, as well as with clearly recorded and certain results. Some general questions, such as that affecting the classification of animals, must be regarded as peculiarly scientific. ”

“ This scientific conception of causation has been developed and rendered definite by the investigations of those physical sciences that can avail themselves of exact experiments and mathematical calculation; and it is there, in Chemistry and Physics, that it is most at home. The conception can indeed be carried into the Biological and Social Sciences, even in its quantitative form, by making the proper allowances. For the limbs of animals are levers, and act upon mechanical principles ”

“ Science did not progress until it rejected all innate ideas or phantasies, and applied itself deeply to its proper methods, to observation, to meditation on the correlation of forces, and to experiment. ”

“ I understand the word science in its old acceptation; a deep rational research into the first principles of things and the origin of our knowledge. At no epoch of history, I dare to say, has this research been carried on by more passionate lovers, by more powerful intelligences, by more magnanimous hearts, than the Mendicant monks of the thirteenth century. ”

“ But then I said and it was the whole purport of my speech, made in the interests of science as well as religion that we can only expect these results from true science, which investigates what Nature really is, and not from a hasty and presumptuous science, which pretends to give us what Nature may be supposed to be. And my criterion of true science, suggested in a phrase, was, that the methods and results of it bear the impress of exactitude or certainty. You remark, as if you did not receive these simple and fundamental principles, that the "exact sciences" are exact, while others are not. ”

“ When will professed scientists, better informed of the close connection between metaphysics and science, whence our modern knowledge of Nature has sprung, better taught in the necessary laws that govern the conflict of reason with the vast unknown, confess that there are realities beyond those they attain? ”

“ Is it not the case that we ourselves, in as far as the delight in knowledge and the enthusiasm for solving riddles have taken hold of us, rejoice in every new piece of elucidation and interpretation that science succeeds in making, that we are in the fullest sympathy with the impulse to understand everything and bring reason and clearness into it, and that we give hearty adherence to the leading ideas which guide the investigations of natural science? ”

“ For complete science, however, we need the aid of every special science,—of Physics, Chemistry, Biology, Physiology, Anatomy, Psychology, and all the other branches which can contribute to any side of our knowledge of nature. ”

“ But in each case and in every similar case the investigation of the newly observed fact proceeds on the assumption that Nature will be found uniform, and on no other assumption can Science proceed at all. ”
