What this book is
The Diamond Lens is a short story by Fitz James O'Brien, an Irish-born writer working in New York. It first appeared in the Atlantic Monthly in 1858. It is told in the first person by a young man named Linley, who has one burning wish: to look deeper into the hidden world of the very small than any human being has looked before.
The tale belongs to the early years of American science fiction. It mixes real microscope science with spiritualism, which was a craze in the 1850s, and with a dark streak of Gothic horror. What does it give you? A fast, strange adventure, a narrator who is both charming and unreliable, and a question that still matters: what does a person owe the world, and other people, when chasing knowledge? Let us begin with the young Linley and the passion that rules his life.

Key point 1 of 6
A boy who dreams of the invisible
The story opens with Linley telling us about himself. Since boyhood he has been drawn to the microscope. As a child he spends hours staring at drops of water, scraps of leaf and the wings of insects, and he feels that each new view is a door opening onto a secret country.
His father, who has little patience for such dreams, wants him to take up a practical trade. Linley has other plans. He studies science, reads everything he can find on optics and the natural world, and grows more sure that the greatest discoveries lie in the tiniest things.
When his father dies, Linley receives a fair inheritance. He moves to New York and spends much of it on the best microscopes money can buy. He is not a rich man by habit, but he treats his money as fuel for his single passion.
This early section sets the tone. Linley is eloquent, witty and a little vain, and he speaks to us like a man confiding in a friend. We like him at once. Yet even here we sense that his love of science is turning into something closer to hunger, and that this hunger will push him past the limits most people respect.
