John Piper:
We aim to enable and to motivate the student
- to observe his subject matter accurately and thoroughly,
- to understand clearly what he has observed,
- to evaluate fairly what he has come to understand,
- to appropriate wisely in life what he has found valuable, and
- to express in speech and writing what he has seen, understood, evaluated, and appropriated in such a way that its accuracy, clarity, fairness, and value can be known and enjoyed by others.
