Industrial Society is not merely one containing 'industry,' large-scale productive units capable of supplying man's material needs in a way which can eliminate poverty: it is also a society in which knowledge plays a part wholly different from that which it played in earlier social forms, and which indeed possesses a quite different type of knowledge. Modern science is inconceivable outside an industrial society: but modern industrial society is equally inconceivable without modern science. Roughly, science is the mode of cognition of industrial society, and industry is the ecology of science.
