We do not go to cowards for tender dealing; there is nothing so cruel as panic; the man who has least fear for his own carcase, has most time to consider others.
Why, thou knowest I am as valiant as Hercules, but beware instinct. The lion will not touch the true prince. Instinct is a great matter. I was a coward on instinct.
The truth is that cowardice itself is violence of a subtle type and therefore dangerous and far more difficult to eradicate than the habit of physical violence.
God will not have his work made manifest by cowards. Always, always, always, always, always do what you are afraid to do. Do the thing you fear and the death of fear is certain.
