Brainpickings put me onto this timeless wisdom from famous eccentric James T. Mangan’s 1936 book You Can Do Anything!
14 Ways to Acquire Knowledge:
Consider the knowledge you already have — the things you really know you can do. They are the things you have done over and over; practiced them so often that they became second nature. Every normal person knows how to walk and talk. But he could never have acquired this knowledge without practice. For the young child can’t do the things that are easy to older people without first doing them over and over and over.
Most of us quit on the first or second attempt. But the man who is really going to be educated, who intends to know, is going to stay with it until it is done. Practice!
Any normal child, at about the age of three or four, reaches the asking period, the time when that quickly developing brain is most eager for knowledge. “When?” “Where?” “How?” “What?” and “Why?” begs the child — but all too often the reply is “Keep still!” “Leave me alone!” “Don’t be a pest!”
Those first bitter refusals to our honest questions of childhood all too often squelch our “Asking faculty.” We grow up to be men and women, still eager for knowledge, but afraid and ashamed to ask in order to get it.
Every person possessing knowledge is more than willing to communicate what he knows to any serious, sincere person who asks. The question never makes the asker seem foolish or childish — rather, to ask is to command the respect of the other person who in the act of helping you is drawn closer to you, likes you better and will go out of his way on any future occasion to share his knowledge with you.
Ask! When you ask, you have to be humble. You have to admit you don’t know! But what’s so terrible about that? Everybody knows that no man knows everything, and to ask is merely to let the other know that you are honest about things pertaining to knowledge.
Animals have knowledge. But only men can reason. The better you can reason the farther you separate yourself from animals.
The process by which you reason is known as logic. Logic teaches you how to derive a previously unknown truth from the facts already at hand. Logic teaches you how to be sure whether what you think is true is really true.
Logic is the supreme avenue to intellectual truth. Don’t ever despair of possessing a logical mind. You don’t have to study it for years, read books and digest a mountain of data. All you have to remember is one word — compare.
Compare all points in a proposition. Note the similarity — that tells you something new. Note the difference — that tells you something new. Then take the new things you’ve found and check them against established laws or principles.
This is logic. This is reason. This is knowledge in its highest form.
