George Steiner

I believe that a work of art, like metaphors in language, can ask the most serious, difficult questions in a way which really makes the readers answer for themselves; that the work of art far more than an essay or a tract involves the reader, challenges him directly and brings him into the argument.

American Critic

George Monbiot

Places that have become agricultural deserts, trashed by giant corporations, could be reforested, drawing carbon dioxide from the air on a vast scale. The ecosystems of land and sea could recover, not just in pockets but across great tracts of the planet.

British Writer

Richard Branson

I love creating hideaways. My idea is to go to the most beautiful, unspoilt places, buy the land, and make sure it is never damaged. I've always admired John D. Rockefeller, who bought up tracts of land to ensure they were left wild in perpetuity.

British Businessman

John Burnside

Scottish Writer

Frank Gehry

American Architect

Thomas Hobbes

War consisteth not in battle only, or the act of fighting; but in a tract of time, wherein the will to contend by battle is sufficiently known.

English Philosopher

Gordon B. Hinckley

The most persuasive gospel tract is the exemplary life of a faithful Latter-day Saint.

American Clergyman

Ursula K. Le Guin

I don't write tracts, I write novels. I'm not a preacher, I'm a fiction writer.

American Writer

Jami Attenberg

No matter how many feminist tracts you read, you never forget what boys like.

American Author

Tim LaHaye
