Note, 1. It is wisdom to be cautious. Every prudent discreet man does all with knowledge (considering with himself and consulting with others), acts with deliberation and is upon the reserve, is careful not to meddle with that which he has not some knowledge of, not to launch out into business which he has not acquainted himself with, will not deal with those that he has not some knowledge of, whether they may be confided in.
He is still dealing in knowledge, that he may increase the stock he has. 2. It is folly to be rash, as the fool is, who is forward to talk of things he knows nothing of and undertake that which he is no way fit for, and so lays open his folly and makes himself ridiculous.
He began to build and was not able to finish.
