A Man Has No Reason To Be Ashamed Of Having An Ape For His Grandfather. If There Were An Ancestor Whom I Should Feel Shame In Recalling It Would Rather Be A Man Who Plunges Into Scientific Questions With Which He Has No Real Acquaintance, Only To Obscure Them By An Aimless Rhetoric.

For These Two Years I Have Been Gravitating Towards Your Doctrines, And Since The Publication Of Your Primula Paper With Accelerated Velocity. By About This Time Next Year I Expect To Have Shot Past You, And To Find You Pitching Into Me For Being More Darwinian Than Yourself.

Make Up Your Mind To Act Decidedly And Take The Consequences. No Good Is Ever Done In This World By Hesitation.
