in short, to be developed by time, as those who come after us shall find expedient. They will be more advanced than we are, in science and in useful arts, and will know best what will suit the circumstances of their day.
This is a loaded statement that can be taken in a number of ways. This paragraph talks about the combination of sciences, the number of professors, and their salaries. However, it also leaves the future in the hands of "those who come after them." I feel like this engagements program is a great example of this. Mixing sciences and taking professors from their usual areas to do something new challenges the way the university was founded, but also gives it more depth. The writers were right when they said we would be more advanced than them, and something like the New College Curriculum may be something that "suits the circumstances of our day."
