It is easier to know man in general than to understand one man in particular

In studying the character and works of a great man, it is always desirable to learn in what he is distinguished from others, and what have been the causes if this difference.

If I want to understand an individual human being, I must lay aside all scientific knowledge of the average man and discard all theories in order to adopt a completely new and unprejudiced attitude. I can only approach the task of understanding with a free and open mind, whereas knowledge of man, or insight into human character, presupposes all sorts of knowledge about mankind in general.

It is more vital to study men than books

It's always important to take time to study men — important men. Friends and enemies.

how easily a man who has never been in any great distress, may pass through life without knowing, in his own person at least, anything of the possible goodness of the human heart - or, as I must add with a sigh, of its possible vileness. So a thick curtain of manners is drawn over the features and expression of men's natures, that to the ordinary observer, the two extremities, and the infinite field of varieties which lie between them, are all confounded - the vast and multitudinous line of differences expressed in the gamut or alphabet of elementary sounds.

Men can know the nature of things

The proper study of Mankind is Man

Indeed, we can always better understand and appreciate a man's real character by the manner in which he conducts himself towards those who are the most nearly related to him, and by his transaction of the seemingly commonplace details of daily duty, than by his public exhibition of himself as an author, an orator, or a statesman.

A man must learn to understand the motives of human beings, their illusions, and their sufferings.

Men judge more from appearances than reality. All men have eyes, but few have the gift of penetration.
Everyone sees your exterior, but few can
discern what you have in your heart.

More observe the characters of men than the order of things: to the one we are formed by Nature, and by that sympathy from which we are so strongly led to take a part in the passions and manners of our fellow-men; the other is, as it were, foreign and extrinsical.

There is no telling what a human character is. Until the test comes. To most of us the test comes early in life. A man is confronted quite soon with the necessity to stand on his own feet, to face dangers and difficulties and to take his own line of dealing with them. It may be the straight way, it may be the crooked way — - whichever it is, a man usually learns early just what he is made of.

Go in confidence, study the rules, and above all things, study human nature for the proper study of mankind is man and you will find that while expanding the intellect and the muscles your enlarged experience will enable you to every day accumulate more and more principle which will increase itself by interest and otherwise until you arrive at a state of independence.
