If a nonnegative quantity was so small that it is smaller than any given one, then it certainly could not be anything but zero. To those who ask what the infinitely small quantity in mathematics is, we answer that it is actually zero. Hence there are not so many mysteries hidden in this concept as they are usually believed to be. These supposed mysteries have rendered the calculus of the infinitely small quite suspect to many people. Those doubts that remain we shall thoroughly remove in the following pages, where we shall explain this calculus.

Rollo May

Rollo May

Rollo May (April 21, 1909, Ada, Ohio - October 22, 1994, Tiburon, California) was an American existential psychologist, authoring the influential book Love and Will in 1969.

Although he is often associated with humanistic psychology, he differs from other humanistic psychologists such as Virginia Satir, Abraham Maslow or Carl Rogers in showing a sharper awareness of the tragic dimensions of human existence. May was a close friend of the U.S. German-born theologian Paul Tillich. His works include Love and Will and The Courage to Create, the latter title honoring Tillich's The Courage to Be.
