While discussing the question why the industrial revoluion was delayed in India for more than a century and a half, it is pertinent to analyse the social attitudes of principal trading communities. Such an analysis may give us an insight into their outlook towards social changes and enable us to discover factors responsible for the non-development of the spirit of scientific inquiry among them. This is important if we bear in mind the fact that the scientific revolution preceded and made possible the industrial revolution. For the present purpose I have selected the Jains, the Vaiśyas and the Khatris. These operated primarily in Gujarat, Rajasthan and north India and controlled the major portion of trade and allied activities.
