But the moment for wider fame and a greater usefulness was now at hand. In the autumn of 1827 she had read Mrs. Marcet's _Conversations on Political Economy_, and had become aware that the subject which she had thought out for herself, and treated in her little stories of _The Rioters_, and _The Turn-Out_, was a recognized science. She followed this up by a study of Adam Smith, and other economists, and the idea then occurred to her that it might be possible to illustrate the whole system of political economy by tales similar in style to those she had already written. The thought had lain working in her mind for long, and, in this autumn of 1831, the idea began to press upon her as a duty. There were many reasons why it was especially necessary just then that the people should be brought to think about Social Science. The times were bitter with the evils arising from unwise laws. None knew better than she did how largely the well-being of mankind depends upon causes which cannot be affected by laws. It is individual conduct which must make or mar the prosperity of the nation. But, on the other hand, laws are potent, both as direct causes of evil conditions (and in a less degree of good conditions), and from their educational influence upon the people. Harriet Martineau felt that she had come to see more clearly than the masses of her fellow-countrymen exactly how far the miseries under which English society groaned were caused directly or indirectly by mischievous legislative acts. Moreover, the circumstances of the moment made the imparting of such knowledge not only possible, but specially opportune. The Bishops had just thrown out the Reform Bill; but no person who watched the temper of the time could doubt that their feeble opposition would be speedily swept aside, and that self-government was about to be extended to a new class of the people. Most suitable was the occasion, then, for offering information to these upon the science and art of society. Harriet was right in her judgment when she started her project of a series of tales illustrative of Political Economy, under a "thorough, well-considered, steady conviction that the work was wanted, was even craved for by the popular mind." She began to write the first of her stories. The next business was to find a publisher to share her belief that the undertaking would be acceptable to the public. She wrote to one after another of the great London publishers, receiving instant refusal to undertake the series from all but two; and even these two, after giving her a little of that delusive hope which ends by plunging the mind into deeper despair, joined with their brethren in declining to have anything to do with the scheme.
