A guided questionnaire to help us progress towards emotional maturity and encourage us to live up to our full potential.

In these days of numerous text-books the author who dares still further to increase the number owes to the public, at least, an explanation in which he shall set forth his purpose, however far short of accomplishment he may have fallen.

Accordingly, in this volume, the author's hopes have been: –

(i) To prepare a text-book adapted to the needs of first-year students in physics at Northwestern University. One fear in this connection is that the transfer of a course of lectures from flexible...

Wherein Antoninus recordeth, What and of whom, whether Parents, Friends, or Masters; by their good examples, or good advice and counsel, he had learned:

Divided into Numbers or Sections.

ANTONINUS Book vi. Num. xlviii. Whensoever thou wilt rejoice thyself, think and meditate upon those good parts and especial gifts, which thou hast observed in any of them that live with thee:

as industry in one, in another modesty, in another bountifulness, in another some other thing. For nothing can so much...

"Parables from Nature", a collection includes all 29 stories from the first, second, third, and fourth series, originally published in separate volumes for children that ages 6-12.

"THERE are two books," says Sir Thomas Browne, in his Religio Medici, "from whence I collect my divinity; besides that written one of God, another of his servant, Nature—that universal and public manuscript that lies expanded unto the eyes of all: those that never saw Him in the one have discovered Him in the o...

The three fixed lights, or windows, subsequently exchanged for our lesser luminaries, were explained one hundred and fifty years ago to signify "the three Persons, Father, Son, Holy Ghost; " and were used to find out the meridian, "when the sun leaves the south, and breaks in at the west window of the Lodge." While the "mossy bed," the ancient signs of disgust and recognition, as well as the primitive name of a Master Mason, are equally obscure at the present day; having been swept away, alon...

The present work is constructed on the same plan as my treatise on Plane Trigonometry, to which it is intended as a sequel; it contains all the propositions usually included under the head of Spherical Trigonometry, together with a large collection of examples for exercise. In the course of the work reference is made to preceding writers from whom assistance has been obtained; besides these writers I have consulted the treatises on Trigonometry by Lardner, Lefebure de Fourcy, and Snowball, an...

In the Chapter on ‘Propositions of Existence’ I have adopted a new ‘normal form,’ in which the Class, whose existence is affirmed or denied, is regarded as the Predicate, instead of the Subject, of the Proposition, thus evading a very subtle difficulty which besets the other form.

These subtle difficulties seem to lie at the root of every Tree of Knowledge, and they are far more hopeless to grapple with than any that occur in its higher branches. For example, the difficulties of the F...

Among the notable books of later times-we may say, without exaggeration, of all time--must be reckoned The Confessions of Jean Jacques Rousseau. It deals with leading personages and transactions of a momentous epoch, when absolutism and feudalism were rallying for their last struggle against the modern spirit, chiefly represented by Voltaire, the Encyclopedists, and Rousseau himself--a struggle to which, after many fierce intestine quarrels and sanguinary wars throughout Europe and America, h...
