There are five tests of the evidence of education - correctness and precision in the use of the mother tongue; refined and gentle manners, the result of fixed habits of thought and action; sound standards of appreciation of beauty and of worth, and a character based on those standards; power and habit of reflection, efficiency or the power to do.

When enthusiasm is inspired by reason; controlled by caution; sound in theory; practical in application; reflects confidence; spreads good cheer; raises morale; inspires associates; arouses loyalty, and laughs at adversity, it is beyond price.

Enthusiasm is the dynamics of your personality. Without it whatever you may possess lies dormant: and it is safe to say that nearly every man has more latent power than he ever learns to use. You may have knowledge, sound judgment, good reasoning faculties; but no one - not even yourself - will know it until you discover how to put your heart into thought and action. When a man dies, if he can pass enthusiasm along to his children he has left them an estate of incalculable value.

Always have a book at hand, in the parlor, on the table, for the family; a book of condensed thought and striking anecdote, of sound maxims and truthful apothegms. It will impress on your mind a thousand valuable suggestions, and teach your children lessons of truth and duty. Such a book is a casket of jewels for your household.

Change of opinion is often only the progress of sound thought and growing knowledge; and though sometimes regarded as an inconsistency, it is but the noble inconsistency natural to a mind ever ready for growth and expansion of thought, and that never fears to follow where truth and duty may lead the way.

This should not come as a surprise, for indeed ‘out there’ there is no light and no colour, and there are only electromagnetic waves; ‘out there’ there is no sound and no music, there are only periodic variations of the air pressure; ‘out there’ there is no heat and no cold, there are only moving molecules with more or less mean kinetic energy, and so on. Finally, for sure, ‘out there’ there is no pain.

For the man sound in body and serene of mind there is no such thing as bad weather; every sky has its beauty, and storms which whip the blood do not make it pulse more vigorously.

The poet should size the Particular, and he should, if there be anything sound in it, thus represent the Universal.

Of all intellectual friendships, none are so beautiful as those which subsist between old and ripe men and their younger brethren in science or literature or art. It is by; these private friendships, even more than by public performance, that the tradition of sound thinking and great doing is perpetuated from age to age.

What hypocrites we seem to be whenever we talk of ourselves! Our words sound so humble while our hearts are so proud.

Although music appeals simply to the emotions, and represents no definite images in itself, we are justified in using any language which may serve to convey to others our musical expressions. Words will often pave the way for the more subtle operations of music, and unlock the treasures which sound alone an rifle, and hence the eternal popularity of song.

The secret of all good writing is sound judgment.

A little rebellion now and then... is a medicine necessary for the sound health of government.

I hold it that a little rebellion now and then is a good thing, and as necessary in the political world as storms in the physical. Unsuccessful rebellions, indeed, generally establish the encroachments on the rights of the people which have produced them. An observation of this truth should render honest republican governors so mild in the punishment of rebellions as not to discourage them too much. It is a medicine necessary for the sound health of government.

No one ever regarded the first of January with indifference. It is that from which all date their time, and count upon what is left. It is the nativity of our common Adam. Of all sound of bells (bells the music highest bordering upon heaven), most solemn and touching is the peal which rings out the old year. I never heard it without a gathering-up of my mind to a concentration of all the images that have been diffused over the past twelve-month. All I have done or suffered, performed or neglected - in that regretted time. I begin to know its worth as when a person dies. It takes a personal color; nor was it a poetical flight of a contemporary, when he exclaimed: “I saw the skirts of the departing year.” It is no more than what is sober sadness, every one of us seems to be conscious of in that awful leave-taking.

And in the end, through the long ages of our quest for light, it will be found that truth is still mightier than the sword. For out of the welter of human carnage and human sorrow and human weal the indestructible thing that will always live is a sound idea.

It doesn’t take a majority to make a rebellion; it takes only a few determined leaders and a sound cause.

The language of the child is silence transformed into sound: the language of the adult is sound that seeks for silence.

The Cosmos has had no beginning... and this is warrant for its continued existence. Why should there be in the future a change that has not yet occurred? The elements there are not worn away like beams and rafters: they hold sound for ever, and so the All holds sound. And even supposing these elements to be in ceaseless transmutation, yet the All persists: the ground of all the change must itself be changeless.

Our responsibility as educators is to teach youth to have respect for those who differ from the customary ways as well as for those who conform. In simpler words, we have a profound obligation both to education and to society itself to support and strengthen the right to be different, and to create a sound respect for intellectual superiority.
