filled the whole earth with the splendour of his teaching. There is no part of philosophy which he did not handle with acuteness and solidity. He wrote about the laws of reasoning; about God and incorporeal substances; about man and other things of sense; and about human acts and their principles.

These conclusions have the very widest reach, and contain, as it were, in their bosom the seeds of truths wellnigh infinite in number. These have to be unfolded with most abundant fruits in their own time by the teachers who come after him.

With his own hand he vanquished all errors of ancient times; and still he supplies an armoury of weapons which brings us certain victory in the conflict with falsehoods ever springing up in the course of years.

For these causes, especially in former days, men of the greatest learning and worthy of the highest praise both in theology and philosophy, having sought out with incredible diligence the immortal writings of Thomas, surrendered
