Is he who says, "it can't be done

In solemn pride his stands aloof

And greets each venture with reproof.

Had he the power he'd efface

The history of the human race;

We'd have no radio or motor cars,

No streets lit by electric stars;

No telegraph nor telephone

We'd linger in the age of stone

The world would sleep if things were run

By men who say "It can't be done".
