This was the more obviously his idea, as we find him reluctantly granting permission for ministerial excursions through a country, if thereby the Fathers' influence in a great city be likely to suffer. He writes to Father Kessel, the Rector at Cologne, where as yet the Society had no college of its own, that "under the circumstances he approves of Kessel's making a short excursion through the province, provided he and his companions are not long absent from the city, and do not sacrifice the main thing to what is accessory; but he does not give them permission to fix their abode out of the town, because places of less importance afford fewer occasions of gathering the desired fruit: and, besides, they must not leave so famous a university; their exertions will be more useful for the good of religion, in forming scholars to become priests and officers of the State, than all the pains they may bestow on the small towns and villages."[33] Again, when in 1547 he had accepted the donation of a church, buildings, and gardens at Tivoli from Louis Mendosa, he found the place not suited to the convenience of scholars; it was too near Rome, and yet too far; subsequently, the institution had to be transferred within the city."[34] Fourthly, in addition to these material and local conditions for the normal conduct of colleges, it is supposed that the external relations of political society are so far favorable, as at least to tolerate freedom of action on the part of this educational Institute. Such toleration was, as a general rule, not only the least that could be asked for, but the most that was enjoyed. These are the chief conditions, material and temporal, which Ignatius requires. They give him a footing to commence his work, and allow the animating principles of his Institute to come into play. The animating principles, to which I refer, may be reduced to three brief heads: First, an intellectual and moral scope, clearly defined, as I shall explain in the following chapters. Secondly, the distinct intention to promote rather the interests of public and universal order and enlightenment, than a mere local good of any city, country, province. Thirdly, a tendency in the intellectual institution itself to become rather a great one than a small one, with more degrees of instruction, more and more eminent Professors, a greater number of the right kind of scholars.[35]
