A study of this anthology is a study of life—of science, art, psychology, philosophy, etc., as the titles show. As you will see in the following pages, many of the articles draw the reader into another milieu—a milieu that was the precursor of today’s. There we discern the hopes, fears, and anxieties that moved powerful minds. And there we find the solutions they proposed and the hopes they cherished regarding humanity’s future. We see a recent past through some of the clearest eyes of that period, and we also get a glimpse of the world they thought would soon emerge. Thus we are able to compare all that with the present, understand better what is happening now, and ponder over the future.
