John Stuart Mill Quote

But he, with these burthens on him, planned, commenced, and completed, the History of India; and this in the course of about ten years, a shorter time than has been occupied (even by writers who had no other employment) in the production of almost any other historical work of equal bulk, and of anything approaching to the same amount of reading and research. And to this is to be added, that during the whole period, a considerable part of almost every day was employed in the instruction of his children: in the case of one of whom, myself, he exerted an amount of labour, care, and perseverance rarely, if ever, employed for a similar purpose, in endeavouring to give, according to his own conception, the highest order of intellectual education.
