Method of scientific investigation

The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind. It is simply the mode at which all phenomena are reasoned about, rendered precise are exact. There is no more difference, but there is just the same kind of difference between the mental operations of a man of science and those of an ordinary person as there is between the operations are methods of a baker or of a butcher weighing out his goods in common scales, and the operations of chemist in performing a difficult and complex analysis by means of his balance and finely-graduated weights. It is not that the action of the scales in the one case, and the balance in the other differ in the principles of their construction of manner of working; but the same beam of one is set on an infinity finer axis than the other, and of course turns by the addition of a much smaller weight. You have all heard it repeated, I dare of the that men of science work by means of induction and deduction, and that by the help of these operations, they, in a sort of sense, wring from Nature certain other things, which are called natural laws, and causes, and that out of these, by some cunning skill of their own, they build up hypotheses and theories. And it is imagined by many, that the operations of the common mind can by no means be compared with these processes, and that they have to be acquired by a sort of special apprenticeship to the craft. To hear all these large words, you would think that the mind of a man of science must be constituted differently from that of his fellow men; but if you will not be frightened by terms, you will discover that you are quite wrong,, and that all these terrible apparatus and being used by yourselves every day and every hour of your lives. Dear Readers, this discussion is very very long.Your regards, Abdul Samad
