Mr. Pitt rose, and said, that from the first hour of his having had the honour to sit in parliament down to the present, among all the questions, whether political or personal, in which it had been his fortune to take a share, there had never been one in which his heart was so deeply interested as in the present; both, on account of the serious principles it involved, and the consequences connected with it.

The present was not a mere question of feeling.  The argument, which ought, in his opinion, to determine the committee, was, that the Slave Trade was unjust.  It was, therefore, such a trade as it was impossible for him to support, unless it could be first proved to him, that there were no laws of morality binding upon nations; and that it was not the duty of a legislature to restrain its subjects, from invading the happiness of other countries, and from violating; the fundamental principles of justice.

Several had stated the impracticability of the measure before them.  They wished to see the trade abolished; but there was some necessity for continuing it, which they conceived to exist.  Nay, almost every, one, he believed, appeared to wish that the further importation of slaves might cease, provided, it could be made out that, the population of the West Indies could be maintained without it.  He proposed, therefore, to consider the latter point; for, as the impracticability of keeping up the population there appeared to operate as the chief objection, he trusted that, by showing it to be ill founded, he should clear away all other obstacles whatever; so that, having no ground either of justice or necessity to stand upon, there could be no excuse left to the committee for resisting the present motion.

He might reasonably, however, hope that they would not reckon any small or temporary disadvantage, which might arise from the abolition, to be a sufficient reason against it.  It was surely not any slight degree of expediency, nor any small balance of profit, nor any light shades of probability on the one side, rather than on the other, which would determine them on this question.  He asked pardon even for the supposition.  The Slave Trade was an evil of such magnitude, that there must be a common wish in the committee at once to put an end to it, if there were no great and serious obstacles.  It was a trade, by which multitudes of unoffending nations were deprived of the blessings of civilization, and had their peace and happiness invaded.  It ought, therefore, to be no common expediency, it ought to be nothing less than the utter ruin of our islands, which it became those to plead, who took upon them to defend the continuance of it.

He could not help thinking that the West India gentlemen had manifested an over great degree of sensibility as to the point in question; and that their alarms had been unreasonably excited upon it.  He had examined the subject carefully for himself:  and he would now detail those reasons, which had induced him firmly to believe, not only that no permanent mischief would follow from the abolition, but not even any such temporary inconvenience as could be stated to be a reason for preventing the House from agreeing to the motion before them; on the contrary, that the abolition itself would lay the foundation for the more solid improvement of all the various interests of those colonies.
