Transition from common to philosophical moral rational cognition

It is impossible to think of anything at all in the world, or indeed even beyond it, that could be taken to be good without limitation, except a good will. Understanding, wit, judgement and whatever else the talents of the mind may be called, or confidence, resolve and persistency of intent, as qualities of temperament, are no doubt in many respects good and desirable; but they can also be extremely evil and harmful if the will that is to make use of these gifts of nature, and whose distinctive constitution is therefore called character, is not good. It is just the same with gifts of fortune. Power, riches, honour, even health, and the entire well-being and contentment with one's condition, under the name of happiness, inspire confidence and thereby quite often overconfidence as well, unless a good will is present to correct and make generally purposive their influence on the mind, and with it also the whole principle for acting; not to mention that a rational impartial spectator can nevermore take any delight in the sight of the uninterrupted prosperity of a being adorned with no feature of a pure and good will, and that a good will thus appears to constitute the indispensable condition even of the worthiness to be happy.
