Some readers may object to calling the last case prejudice. They may

say that Sedgwick was perfectly justified. That, however, is not the

present question. Prejudice itself may sometimes be justified. But

Sedgwick tacitly admitted that he not only believed the shell had not

been imbedded, he actually _desired_ that it had not been. And our

desires always determine, to a great extent, the trouble we take to get

evidence, and the importance we attach to it after we have it.

Emerson’s remark, that inconsistency is the hobgoblin of little minds,

is true in a double sense. For not only is it harmful to fear to

change an opinion which we have entertained, it is even harmful at

times to fear to hold simultaneously two opinions incongruous with

one another. If a thought springs up in your mind, and you come to

see after a time that it is inconsistent with another thought, do not

immediately try to throw out one or the other. Instead, think the new

thought out in all its bearings and implications, just as if you had

never had the first. Perhaps follow the same practice with the first

idea. By and by one will reveal its falsity and the other its truth.

Or more likely you will find that there was some truth in each idea,

and you will reconcile the two in a truth higher, deeper, or more

comprehensive.

I have set down these three cases of prejudice to help the reader in

recognizing the same or similar prejudices in himself. And the mere

recognition of prejudices as prejudices will do much toward their

elimination. But though we all strenuously maintain our anxiety to get

rid of prejudices, the real reason most of us have them is that we do

not want to get rid of them. We are all willing to get rid of prejudice

in the abstract. But when some one troubles himself to point out any

particular concrete prejudice of ours we defend it and cling to it

like a dog to his bone. The only way we can get rid of this desire

to cling to our prejudices, is thoroughly to convince ourselves of

the superiority of the truth; to leave not the slightest doubt in our

own minds as to the value of looking with perfect indifference on all

questions; to see that this is more advantageous than believing in

that opinion which would benefit us most if true, more important than

“being consistent,” more to be cherished than the comfortable feeling

of certainty. When we really do desire to get rid of our prejudices we

will put ourselves on the path of getting rid of them. And not before

then.

One more prejudice has yet to be considered. This may be called the

prejudice of imitation. We agree with others, we adopt the same

opinions of the people around us, because we fear to disagree. We fear

to differ with them in thought in the same way that we fear to differ

with them in dress. In fact this parallel between style in thought

and style in clothing seems to hold throughout. Just as we fear to

look different from the people around us because we will be considered

freakish, so we fear to think differently because we know we will be

looked upon as “queer.” If we have a number of such dissenting opinions

we will be regarded as anything from a mere crank to a fanatic or one

with a “screw loose.” When our backs are turned people will wisely

point their index fingers to their temples and move them around in

little circles.

Our fear of freak opinions is only equalled by our dread of ideas

old-fashioned. A little while ago it was considered popular to laugh

at the suffragettes. And everybody laughed. Now it is getting to be

popular to laugh at the anti-suffragettes. A little while ago it was

considered quite _comme il faut_ to fear socialism. Now it is becoming

proper to remark, “There is really quite a good deal of truth in their

theories.” And soon we shall doubtless all be out and out socialists.

Nor is the prejudice of imitation confined to the layman. If anything,

it is even more common among so-called “thinkers.” I remember

quoting some remark of Spencer to an acquaintance, and getting this:

“Yes, but isn’t Herbert Spencer’s philosophy considered dead?” This

same acquaintance also informed me that John Stuart Mill had been

“superseded.” He candidly admitted—in fact seemed rather proud of the

fact—that he had read practically nothing of either philosopher. I am

not trying to defend Spencer or John Stuart Mill, nor am I attempting

to bark at the heels of any of our present-day philosophers. But I am

willing to wager that most of these same people now so dithyrambic in

their praise of James, Bergson, Eucken and Russell will twenty-five

years hence be ashamed to mention those names, and will be devoting

themselves solely to Post-neofuturism, or whatever else happens to be

the passing fadosophy of the moment.

If this is the most prevalent form of prejudice it is also the most

difficult to get rid of. This requires moral courage. It requires the

rarest kind of moral courage. It requires just as much courage for a

man to state and defend an idea opposed to the one in fashion as it

would for a city man to dress coolly on a sweltering day, or for a

young society woman to attend a smart affair in one of last year’s

gowns. The man who possesses this moral courage is blessed beyond

kings, but he must pay the fearful price of ridicule or contempt.

There is another form of this prejudice of imitation radically opposed

to this. Just as with fashions in clothes there are people who strive

to imitate others, so there are people who devote themselves entirely

to being “different.” Their greatest fear is that they will be taken

for “one of the mob.” They dress themselves as uniquely as possible

in order to acquire “individuality.” We have these same people in

the realm of thought. They are in constant trepidation lest they say

something that everybody else says. They say things not for the sake

of truth but for humor or paradox. Their great delight is to affirm or

defend something “new” regardless of its truth; something deliciously

radical which will shock everybody else and startle even themselves.

The worst part of this is that these people gradually come to regard

their propositions as true, just as a liar finally comes to believe his

own lies.

The only cure for such a mental condition is a constant sincerity in

every opinion we advance. People are often led into the fault by a

motive not incommendable in itself—the desire for originality. But

they choose the wrong path to their goal. If you make originality and

radicalness your aim, you will attain neither truth nor originality.

But if you make truth your aim you will very likely get truth, and

originality will come of itself.

There are hundreds of prejudices, hundreds of forms of prejudice.

There is, for instance, the prejudice of conservatism, which manifests

itself in a vague fear that if the present order were changed in any

particular—if women were given the vote, if socialism were to triumph,

if a new filing system were to be installed at the office—all would be

lost. But I cannot deal adequately with all the forms of bias which

flock to mind.

The distinguishing mark of the great thinkers of the ages was their

comparative freedom from the prejudices of their time and community.

In order to avoid these prejudices one must be constantly and

uncompromisingly sounding his own opinions. Eternal vigilance is the

price of an open mind.

* * * * *

Prejudice is not the only danger which lies in wait for the would-be

thinker. In his very efforts to get rid of prejudice he is liable to

fall into an even greater intellectual sin. This sin is uncertainty.

As uncertainty and doubt are nearly synonymous, the reader will

probably be surprised at this statement because of the praise I have

hitherto accorded to the doubtful attitude. But the doubtful attitude,

necessary and praiseworthy as it is, should not be maintained always.

We think in order to have opinions. We have opinions in order to guide

action; in order to act upon should occasion require. Herbert Spencer,

even after his remarks quoted at the beginning of this chapter, which

imply the need of extreme caution, adds, “. . . In daily life we are

constantly obliged to act out our inferences, trustless as they may

be— . . . in the house, in the office, in the street, there hourly

arise occasions on which we may not hesitate; seeing that if to act is

dangerous, never to act at all is fatal. . . .”

There are other reasons why we cannot afford to keep the doubtful

attitude. If our lives were interminable, if we had limitless time for

thinking, we could afford to remain in doubt indefinitely. But life is

fleeting. So if you have examined facts obtainable on such a question

as psychic phenomena, have kept your mind open for a certain time, and

have decided that communication with the dead is impossible, you are

justified in discontinuing to look for evidence on that question. Every

hour devoted to examining such evidence would be an hour taken away

from thought on some other subject, and the law of diminishing returns

is just as applicable in thinking as in economics.

Another trouble with the attitude of doubt is that when not properly

utilized it hinders rather than aids the acquisition of truth. This is

especially the case when it takes the form of _fear of prejudice_. If

guided by this fear, in our anxiety not to discriminate in favor of one

side of a question we are apt to discriminate in favor of the other.

In an attempt to give an opposing argument due consideration, we are

liable to give it undue consideration. Instead of removing prejudice

with reason we may be trying to balance one prejudice with a counter

prejudice. When a person disagrees with him, a very conscientious

thinker, fearing that he may be prejudiced, and in order to prove

himself broad-minded, will often say regarding an objection, “Well,

there may be something in that.” Now your only excuse for ever saying,

“There may be something in that,” will be as an attitude to assume in

experimenting or observing, or looking up material or arguments to find

whether there actually _is_ anything in it. Then, if you do not find

anything in it you are justified in saying so—and you ought to.

It is useless to stimulate doubt unless you intend, on grounds

of reason, to settle the doubt. _The doubtful attitude should be

maintained only so long as you are actively searching for evidence

bearing on a question._ Maintained at any other time or used in any

other way it means merely uncertainty, indefiniteness, vagueness, and

leads nowhere.

It is important that we be unprejudiced. It is even more important that

our views be definite. And if our definite views are wrong? . . . But

the words of Thomas Huxley on this subject cannot be improved:

“A great lawyer-statesman and philosopher of a former age—I mean

Francis Bacon—said that truth came out of error much more rapidly

than it came out of confusion. There is a wonderful truth in that

saying. Next to being right in this world, the best of all things

is to be clearly and definitely wrong, because you will come out

somewhere. If you go buzzing about between right and wrong, vibrating

and fluctuating, you come out nowhere; but if you are absolutely and

thoroughly and persistently wrong, you must, some of these days, have

the extreme good fortune of knocking your head against a fact, and that

sets you all straight again.”[13]

When you find yourself fluctuating back and forth between two opinions

you might find it helpful to hold an internal debate. State to yourself

as strongly as possible the case for the affirmative, and then put

as convincingly as possible the case for the negative, holding a

refutation if necessary. You may even elaborate this by writing the

arguments for both sides in parallel columns. Of course you should

never use an argument which you can see on its face to be fallacious,

nor a statement which represents merely a prejudice and nothing more.

You should use only such arguments as you think a sincere debater would

conscientiously employ. By thus making your reasons articulate you will

often find that there is really no tenable case at all for one side,

and you will seldom fail to reach a definite conclusion. This method of

arriving at a decision may be voted childish and even artificial, but

nothing is to be despised which can render intellectual help.

One word more on this. There is a type of individual, most often met

with among writers, who fears to make a statement of his thought

definite, because he has a faint suspicion that it may be wrong.

He wishes to allow himself plenty of loopholes to slip out of an

intellectual position in case any one should attack it. Hence he never

says outright, “Such and such is the case.” Instead, his talk or

writing is guarded on all sides by such expressions as “It is probable

that,” “it is possible that,” “the facts _seem_ to indicate that”; or

“such and such is _perhaps_ the case.” Not satisfied with this he makes

his statement less positive by preceding it with an “I believe,” or

worse yet, with an “_I am inclined_ to believe.”

This is often done under the impression that it is something noble,

that it signifies broadmindedness, lack of dogmatism, and modesty.

It may. If it does, so much the worse for broadmindedness, lack of

dogmatism, and modesty. Never yield to the temptation to word your

thoughts in this manner. If you truly and firmly believe that “such

and such is the case” _say_ “such and such is the case”; not “it is

possible that such and such is the case,” or “such and such is perhaps

the case,” or “it is my belief that such and such is the case.” People

will assume that it is your belief and not somebody else’s.

Suppose you have made a positive statement. And suppose you later find

it to be wrong? Well then, acknowledge that it is wrong. Acknowledge

that you have done something human; that you have done something

which every man before you has done; that you have made a mistake. I

realize such a confession is hard. It is the severest blow you can

deal to yourself, and few people will think the better of you for

doing it. Most of them will say, “See, he acknowledges himself that

he was wrong.” And with these people, both you and your theory will

be far more discredited than if you had clung to it until the end of

your life, no matter how obviously, how flagrantly, it opposed itself

to facts. But a few people will appreciate your sacrifice. A few

people will admire your bigness. And you will grow. You will grow as a

thinker. What is more, you will grow morally. And the time will come

when you will have fewer and fewer occasions to reverse yourself, for

you will learn to think longer before you advocate an opinion.

* * * * *

The question of the avoidance of prejudice and the necessity of

breaking off doubt, remains still unsettled. There can be no doubt

that the two desideratums conflict; that to cut off doubt, or even to

refrain from stimulating it, is to encourage by so much the dominance

of prejudice.

The answer to this question will depend entirely upon the particular

problem under consideration. No rules can be laid down. Everything will

depend upon the importance of the question, upon the possibility or

frequency of occasions when we may be called to act upon the answer,

and upon the way in which the answer will affect conduct when we do act

upon it. Where the importance of the question is trifling, it would be

foolish to sound our prejudices too deeply, or to go to any elaborate

pains to collect evidence. Where immediate, unhesitating action is

required, remaining in doubt might be fatal. Any decision would be

better than no decision. When the importance of the question is vital,

or when the possibility of having to act on the answer is distant,

we can afford to preserve our doubts, to suspend final judgment, for

years—perhaps during our entire life; and we should spare no pains to

investigate fully all that relates to the question.

Just how much trouble to take, how long to keep alive the attitude

of doubt in any particular question, will have to be decided by the

individual. His own judgment must be the sole criterion.

VI

DEBATE AND CONVERSATION

The mind engages in many activities which have power either for evil or

good. Just what influence they will exert depends on how we use them.

One of the most important of these activities is debate.

Debate brings in that unequaled form of incentive for all action which

psychologists call “social pressure” and which here means nothing more

than the desire to excel a fellow-being in some line of endeavor. When

debating we concentrate, and we do so without conscious effort. We are

too interested in defeating our opponent to wander from the subject.

We are forced to think rapidly. Not least of all, we are compelled to

think articulately.

But with all its advantages, debate is one of the most potent sources

of prejudice. In the heat of controversy, we adopt any and every

argument that comes handy. Every statement of our opponent is

considered only in the light of how it can be refuted. We are willing

to use almost any objection against him, so long as we believe he will

see no flaw in it. It is of utmost importance that we find how to avoid

these pitfalls.

The first thing we must do is to adopt a complete change of attitude

toward an opponent’s arguments. Whenever we meet with a fact which

we would not like to cite in a debate; because, to put it mildly, it

would not help our side; we should carefully investigate that fact.

We should consider whether if true it changes the aspect of things.

We should get rid of the idea that in order to vindicate our side we

must answer every contention our opponent advances. For this opponent

of ours will very likely be a man in full possession of his senses; at

least some of his arguments will be rational. When they are, we should

be willing to acknowledge it. Their truth does not necessarily make his

side right. His arguments may be irrelevant; they may be outbalanced by

some other reason or reasons. Attempts to prove too much are liable to

put us into the position of the lawyer whose client is alleged to have

been sued for putting a hole in a borrowed umbrella. The lawyer proved

first, that his client did not borrow the umbrella; second, that there

was a hole in it when he got it; third, that there was nothing the

matter with it when he returned it.

After you have had a friendly argument with an acquaintance, you

take leave either with the satisfaction that you have bested him, or

with a vague consciousness that though you were right, he was just a

trifle more skillful at bringing forward arguments. But having this

satisfaction or dissatisfaction, you seldom think any more of the

matter until the next time you meet him. Now this practice is helpful

neither to your debating nor your thinking. After you have taken

leave of your acquaintance, and are left to the quietude of your own

thoughts, you should mentally run over your controversy. You should

dispassionately consider the bearing and weight of his arguments; and

then, reviewing your own, ask yourself which were valid and relevant

and which were not. If you find you have used a sophism you should

resolve never to use it again, even though your opponent may have

been unable to answer it. The question of morals aside, this is poor

practice if you ever hope to become a thinker. In the end, it will tell

against you even as a debater.

You can use your debates for constructive material as well as for

criticism. After a controversy you can go over the arguments of your

opponent which you could not refute, or refuted but lamely, and think

of the answers you might have given. Of course you should take care

that these answers are not sophistical. The question will very likely

come up again; if not with the same friend, then with another, and when

it does you will find yourself prepared.

But the best debater, or at least he who gets the most from debating,

is the man who looks for evidence and thinks not for debate, but to

obtain a correct conclusion. After he has reached a conclusion in

this manner, he does not advance every possible reason to support it.

He does not even utilize the reasons on which others base a similar

belief, if he does not himself accept these reasons. He states merely

that evidence and those reasons which have led him to accept his

conclusion, nothing more.

While we are considering debate, I may well say a few words about

conversation in general. We do not and cannot always argue with our

friends, even though we scorn the dictums of formal etiquette. But

because we do not argue, it does not follow that we gain nothing. In

fact, ordinary conversation has advantages numerous over debate, not

the least of which is the comparative freedom it gives from prejudice.

But the value of conversation depends both on what we talk about,

and whom we talk with. Too much of our talk is on petty matters, is

uneducative. And even if we converse on worthy topics, it will profit

us little if we do not talk with worthy people. When we commune with a

dull mind, our thoughts are forced, in some degree, down to the level

of that mind. But dull people do not usually talk of weighty matters,

nor do active intellects dwell long on trifles. Therefore if we

rightly choose our companion we can conscientiously leave our path of

conversation to choose itself.

One aspect of conversation remains to be treated—its corrective

power. “There is a sort of mental exposure in talking to a companion;

we drag our thoughts out of their hiding-places, naked as it were,

and occasionally we are not a little startled at the exhibition.

Unexpressed ideas are often carefully cherished until, placed before

other eyes as well as our own, we see them as they really are.”[14]

VII

THINKING AND READING

Up to now I have dealt with thinking almost as if it could be carried

on without external aid. As with cautionary and constructive thought, I

have perhaps been led to do this because of a reaction from the usual

insistence upon reading as indispensable to mental improvement, and the

corresponding neglect of the need for independent thinking. Men thought

before there were books, and men can still think without reading, but

they cannot. . . . I was about to remark that they could not read

without thinking, but on second thought I am inclined to doubt it.

However, we have clung to the natural order, for we first considered

unaided thinking, then the help given by conversation and dispute, and

finally we are to examine the aid rendered by reading. There can be no

doubt that this order follows the development of thought both in the

individual and in the human race.

While no complaint can be made of lack of quantity in what has been

written on reading, most of it has not taken up the subject from the

proper standpoint; still less has dealt with it in the right manner.

There has been counsel galore urging people to read; and recently there

has been a great deal of advice on what to read. But comparatively very

little has been said on _how_ to read. At one time reading was regarded

an untainted virtue, later it was seen that it did us no good unless we

read good books, and now there is a dawning consciousness that even if

we read good books they will benefit us little unless we read them in

the right way.

But even where this consciousness has been felt, little attempt has

been made to solve the problem systematically. Leisurely discourses,

pretty aphorisms, and dogmatic rules have been the forms in which the

question has been dealt with. Such conflicting adages as “A good book

should be read over and over again”; and “The art of reading is the art

of skipping,” are not very serviceable. The necessity of some sort of

orderly treatment is evident.
