Scientific research

“ The most striking, and also the most radical and pervasive, characteristic of our time is, of course, the progress made in scientific knowledge. Month by month enormous numbers of facts are, in every department, added to the knowledge already acquired. To let one’s imagination range, even in a cursory way, over the work that is being done in 38 chemistry and physics merely as they concern biology—to enumerate the subdivisions of these sciences, or to look down a list of recent publications relating to research carried on in them, is enough to make one’s brain reel. ”

“ It is characteristic of the progress of research that as one proceeds the horizon broadens and new questions spring up in the pathway of the investigator. He does not solve the problems he sets out to solve, but opens a lot of new ones. This is one of the features of scientific research that make its votaries characteristically optimistic.
Experimental Work.—Among the recent influences tending to advance biology, none is more important than the application of experiments to biological studies. ”

“ 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. ”

“ Essays on the Result of Scientific Research, as witnessed by the civilization of the Nineteenth Century, which derives so much of its strength and moral excellence from the Steam-engine, the Electric Telegraph, and other applications of scientific principles. ”

“ 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. ”

“ 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. ”

“ It is the aim of the authors of these essays to present the results of experience in scientific investigation, to illustrate by concrete examples the sources of progress in a few departments of knowledge and so make clear to the layman the position of research as a factor in national prosperity. ”

“ It was thought that the temper of the really scientific man, so patient in research, so accurate and conscientious, so slow to dogmatize, so deferential to others, might be fostered by experimental science in the schools, acquiring "knowledge at first hand," making experiments, looking with great respect at balances, weighing and measuring, and giving an account of results. ”

“ He has distinguished himself in the field of original research and experiment, and belongs of right to the select band of scientific men who in these latter days, are so eagerly bringing to the light the laws that govern phenomena in the wonderful world of Nature. ”

“ In the earlier stage of physical research, all observation and experiment lead forward to general results, which gain ready acceptance because they may be said to be involved in scientific procedure itself. ”

“ Such research should be carried on, if possible, in connection with the great body of serious scientific investigations, by persons of proved ability and clear moral sense, and the work should be cordially open to the observation of all earnest friends. ”

“ In addition to this general order of precedence of evolution in point of time, the various sciences are so mutually related that all must advance together, the simple ones taking the lead, and the concrete and more complex sciences, with their attendant arts, following behind. ”

“ The answer which the man of science returns to this question, as to what is the use of his discovery, is, ‘I only tell you what is the interest of that discovery, that interest which compels and impels me to go on in the path of investigation.’ It is knowledge, mere knowledge of the facts and laws of nature, that the scientific mind seeks to gain. ”

“ Whatever subjects involve accessible and observable phenomena, one causing another, or in any way related to another, belong properly to science for investigation. Intellect, feeling, human action, language, education, history, morals, religion, law, commerce, and all social relations and activities, answer to this condition; each has its basis of fact, which is the legitimate subject matter of scientific inquiry. ”

“ 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. ”

“ The popular idea of scientific investigation is a vehement, aimless collection of little facts, collected as a bower bird collects shells and pebbles, in methodical little rows, and out of this process, in some manner unknown to the popular mind, certain conjuring tricks—the celebrated “wonders of science”—in a sort of accidental way emerge. ”

“ Natural science has become so vastly extended, its recorded facts and its unanswered questions so immensely multiplied, that every strictly scientific man must be a specialist, and confine the researches of a whole life within a comparatively narrow circle. ”

“ The legitimate aim of all systematic, exact experiments is to lay a foundation of well-ascertained and closely related facts on which may be developed a superstructure of science to supersede the theoretical speculations which form an important part of the prelude of scientific discovery. ”

“ A clear-cut conception of the purposes and methods of scientific investigation and of the scope of the several sciences is a dearly bought product of generations of well-directed, as also of misdirected, effort. ”

“ It is this study which has given science its present-day prominence. In the world of intellect, doubtless, the most marked features in the history of the past century have been the extraordinary advances in scientific knowledge and investigation, and in the position held by the men of science with reference to those engaged in other pursuits. ”

“ At first it is probable that our principal experimental work must be the illustration of particular branches of science, but as we go on we must add to this the study of scientific methods, the same method being sometimes illustrated by its application to researches belonging to different branches of science. ”

“ The tests which we are making are given for the advancement of science and for the information of the person tested. By scientific means we will be able to separate characteristics derived from heredity and environment and to treat each class separately. ”

“ 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. ”

“ It may be a task, not hopeless, to extract from the past progress of science the elements of an effectual and substantial method of Scientific Discovery. The advances which have, during the last three centuries, been made in the physical sciences;—in Astronomy, in Physics, in Chemistry, in Natural History, in Physiology;—these are allowed by all to be real, to be great, to be striking ”

“ It is to the man of science, who also gives attention to practical questions, and to the practitioner, who devotes part of his time to the prosecution of strictly scientific investigations, that we owe the rapid progress of the present day, both merging more and more into one class, that of pioneers in the domain of Nature. ”

“ 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. ”

“ His contribution to the development of science was abstracting the method of experiment from the concrete problem to see its bearing and importance as a universal method of research. He advocated changing education to include studies of the natural world using observation, exact measurement, and experiments. ”

“ The Study of the Biological and Physical Sciences.—The last century is marked by scientific development along several {466} rather distinct lines as follows: the study of the earth, or geology; animal and vegetable life, or biology; atomic analysis, or chemistry; biochemistry; physics, especially that part relating to electricity and radioactivity; and more recently it might be stated that investigations are carried on in psychology and sociology, while mathematics and astronomy have made progress. ”

“ One remarkable feature in the modern progress of biological science has been the application of improved methods of observation and experiment, and the employment in physiological research of the exact measurements employed by the experimental physicist. ”

“ 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. ”

“ But I would like to call attention here to what appears to me a fundamental condition of scientific work and thereby a necessary result of scientific training. Science is naught if not exact. Accurate observation, accurate record, accurate deduction from data, all of which may be reduced to simple, plain honesty. Anything else is error, not science. ”

“ Science, then, commands our respect, not on the basis that its present assumptions and deductions are absolutely and for all time true, but on the ground that its method is for all time true—the method of discovery, the method of observation, research, experimentation, comparison, examination, testing, analysis and synthesis. ”

“ Although we cannot always isolate our factors, control our processes, and otherwise apply scientific method, with results as conclusive as those obtained in laboratories of chemistry, physics, or biology, we need not therefore reject scientific method in favor of a rule-of-thumb. ”

“ For the conclusions stated in the present work, respecting knowledge and discovery, are drawn from a connected and systematic survey of the whole range of Physical Science and its History; whereas, hitherto, philosophers have contented themselves with adducing detached examples of scientific doctrines, drawn from one or two departments of science. ”

“ So far, indeed, as this persuasion of a connexion among apparently different kinds of agencies, impels men, engaged in the pursuit of knowledge, to collect observations, to multiply, repeat, and vary experiments, and to contemplate the result of these in all aspects and relations, it may be an occasion of the most important discoveries. ”

“ I have been compelled to use the words ‘science’ and ‘scientific’ because these terms have become firmly adherent to a group of subjects such as Physics, Chemistry, Geology, Botany, etc., and cannot now be detached from them. Unfortunately ‘scientific’ is used in another sense as implying accuracy of experimental method and in deduction from results. So that in calling ourselves scientific men we run the risk of seeming to claim a monopoly of method, as though we pretended to be somehow superior to the trained workers in other branches. ”

“ Prominent attention has been also devoted to those various sciences which help to a better understanding of the nature of man, to the bearings of science upon the questions of society and government, to scientific education, and to the conflicts which spring from the progressive nature of scientific knowledge. ”

“ 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. ”

“ But most or all of these reasons have been seen to be of a kind which hold out a good promise for the future, and thereby afford an ample encouragement to the use of a strictly logical method in political investigations, and to the attempt to create a scientific structure of ever-increasing completeness in this region, as well as in others more familiarly associated with the name of Science. ”

“ The sum total of all these researches forms a scientific patrimony, which needs to be known to us, in order that our own conclusions may serve to complete those of other investigators, who have preceded us, and thus form a contribution to science. ”

“ The branches of knowledge are many, but the intellectual faculties employed and the operations carried on in scientific investigation are comparatively few. A mind thoroughly trained in habits of observation, experiment, comparison, abstraction, generalization, and inference, possesses all the fundamental qualifications for undertaking the task of discovering those higher generalizations which unite the different and often seemingly-conflicting conclusions of the several sciences. ”

“ The preliminary discrimination of method is the distribution of all phenomena among certain grand divisions.
⁠7. It is of vital importance to discriminate between a division of phenomena for purposes of study, and a separation of the phenomena thernselves.
⁠8. Since the sciences deal with different aspects of the same objective world, it follows that they must cooperate to give a complete account of reality.
⁠9. Scientific method has been developed historically first in application to inorganic phenomena, then to organic life, more recently to psychical and social phenomena. ”
