tool

is required for work, as neither the naked hand (which gives guiding motion) nor the understanding (which supplies suggestions and cautions) left to themselves can effect much.

Neither the naked hand nor the understanding left to itself can effect much. It is by instruments and helps that the work is done, which are as much wanted for the understanding as for the hand. And as the instruments of the hand either give motion or guide it, so the instruments of the mind supply either suggestions for the understanding or cautions. Francis Bacon
