The current book is a collection of essays, speech transcripts, and reprints that were written and compiled by John Fiske. This text, published in 1899, includes discussions on science, evolution, philosophy, and liberal thought
Sample excerpt from the book: In the course of the year 1774 Dr. Priestley found that by heating red
precipitate, or what we now call red oxide of mercury, a gas was
obtained, which he called "dephlogisticated air," or, in other words,
air deprived of phlogiston, and therefore incombustible. This
incombustible air was _oxygen_, and such was man's first introduction to
the mighty element that makes one fifth of the atmosphere in volume and
eight ninths of the ocean by weight, besides forming one half of the
earth's solid crust, and supporting all fire and all life. I know of
nothing which can reveal to us with such startling vividness the extent
of the gulf which the human mind has traversed within little more than a
hundred years. It is scarcely possible to put ourselves back into the
frame of mind in which oxygen was unknown, and no man could tell what
takes place when a log of wood is burned on the hearth. The language
employed by Dr. Priestley carries us back to the time when chemistry was
beginning to emerge from alchemy.
