The art of scientific investigation

The art of scientific investigation



From Introduction:
Elaborate apparatus plays an important part in the science of today, but I sometimes wonder if we are not inclined to forget that the most important instrument in research must always be the mind of man. It is true that much time and effort is devoted to training and equipping the scientist's mind, but little attention is paid to the technicalities of making the best use of it. 

There is no satisfactory book that systematises the knowledge available on the practice and mental skills — the art — of scientific investigation. 

This lack has prompted me to write a book to serve as an introduction to research. My small contribution to the literature of a complex and difficult topic is meant in the first place for the student about to engage in research, but I hope that it may also interest a wider audience. Since my own experience of research has been acquired in the study of infectious diseases, I have written primarily for the student of that field. But nearly all the book is equally applicable to any other branch of experimental biology and much of it to any branch of science. 

I have endeavoured to analyse the methods by which discoveries have been made and to synthesise some generalisations from the views of successful scientists, and also to include certain other information that may be of use and interest to the young scientist. In order to work this material into a concise, easily understandable treatise, I have adopted in some places a frankly didactic attitude and I may have over-simplified some of the issues. Nothing, however, could be further from my intentions than to be dogmatic. 

I have tried to deduce and state simply as many guiding principles of research as possible, so that the student may have some specific opinions laid before him. The reader is not urged to accept my views, but rather to look upon them as suggestions for his consideration. Research is one of those highly complex and subtle activities that usually remain quite unformulated in the minds of those who practise them. This is probably why most scientists think that it is not possible to give any formal instruction in how to do research.

 Admittedly, training in research must be largely self-training, preferably with the guidance of an experienced scientist in the handling of the actual investigation. Nevertheless, I believe that some lessons and general principles can be learnt from the experience of others.

 As the old adage goes, " the wise man learns from the experience of others, the fool only from his own." Any training, of course, involves much more than merely being "told how". Practice is required for one to learn to put the precepts into effect and to develop a habit of using them, but it is some help to be told what are the skills one should acquire. 

Too often I have been able to do Httle more than indicate the difficulties likely to be met — difficulties which we all have to face and overcome as best we can when the occasion arises. Yet merely to be forewarned is often a help. Scientific research, which is simply the search for new knowledge, appeals especially to people who are individualists and their methods vary from one person to another. A policy followed by one scientist may not be suitable for another, and different methods are required in different branches of science.
