If we can possibly avoid wrecking this little planet of ours, we will, But-there must be risks! There must be. In experimental work there always are!
Danger it selfe the best remedy for danger.
To a crafty man, a crafty and an halfe.
Hell is full of good meanings and wishings.
Nothing secure unlesse suspected.
He that hath love in his brest, hath spurres in his sides.
