A tool is but the extension of a man's hand, and a machine is but a complex tool. And he that invents a machine augments the power of a man and the well-being of mankind.

— Beecher, Henry Ward

Don't force it... get a bigger hammer.

— Bloch, Arthur

Man is a tool-using animal. Without tools he is nothing, with tools he is all.

— Carlyle, Thomas

There is a great satisfaction in building good tools for other people to use.

— Dyson, Freeman

A worker may be the hammer's master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.

— Kundera, Milan

But lo! men have become the tools of their tools.

— Thoreau, Henry David

O God, thy sea is so great, and my boat is so small.
