"Man is a tool-using animal. Weak in himself and of small stature, he stands on a basis of some half square foot, has to straddle out his legs lest the very winds supplant him.

Nevertheless, he can use tools, can devise tools; with these the granite mountain melts into light dust before him; seas are his smooth highway, winds and fire his unwearying steeds.

Nowhere do you find him without tools. Without tools he is nothing, with tools he is all."

- Thomas Carlyle (1795 - 1881)
