An autobiography of Helen Keller published when the author was still in her early 20's. The narrative reveals how her mind developed and matured until she began her studies at Radcliffe College

The World I Live In by Helen Keller is a collection of essays that poignantly tells of her impressions of the world, through her sense of touch, smell, her imagination and dreams. My hand is to me what your hearing and sight together are to you. In large measure we travel the same highways, read the same books, speak the same language, yet our experiences are different. All my comings and goings turn on the hand as on a pivot. It is the hand that binds me to the world of men and women. The hand is my feeler with which I reach through isolation and darkness and seize every pleasure, every activity that my fingers encounter...

"There may seem to be a disappointing lack of prophesy in a book avowedly dealing with the future; but since I believe the women’s movement to be a seeking for knowledge and good, to show what is reasonable and good in the movement is to show what will persist and triumph. Through all our faults and mistakes, we women are aiming at better understanding and co-operation with men, and a better adaptation to one another of conditions and persons. We are having to hammer out for ourselves the right principles of government...

Jules Henri Poincaré (1854–1912) was one of France’s greatest mathematicians and theoretical physicists, and a philosopher of science. As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics, and celestial mechanics. He was responsible for formulating the Poincaré conjecture, one of the most famous problems in mathematics. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory...

Two years, two months and two days! This is what forms the time line of one man's quest for the simple life and a unique social experiment in complete self reliance and independence. Henry David Thoreau published Walden in 1884. Originally drafted as a series of essays describing a most significant episode in his life, it was finally released in book form with each essay taking on the form of a separate chapter. Thoreau's parents were in financial straights, but rich intellectually and culturally...

AMUSEMENTS IN MATHEMATICSby HENRY ERNEST DUDENEYPREFACEIn issuing this volume of my Mathematical Puzzles, of which some have appeared in periodicals and others are given here for the first time, I must acknowledge the encouragement that I have received from many unknown correspondents, at home and abroad, who have expressed a desire to have the problems in a collected form, with some of the solutions given at greater length than is possible in magazines and newspapers. Though I have included a few old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original...

In Defense of Women is H. L. Mencken’s 1918 book on women and the relationship between the sexes. Some laud the book as progressive while others brand it as reactionary. While Mencken didn’t champion women’s rights, he described women as wiser in many novel and observable ways, while demeaning average men. According to Mencken’s biographer, Fred Hobson: Depending on the position of the reader, he was either a great defender of women’s rights or, as a critic labelled him in 1916, ‘the greatest misogynist since Schopenhauer’,'the country’s high-priest of woman-haters.’
