— Stephen Jay Gould"A complete theory of evolution must acknowledge a balance between "external" forces of environment imposing selection for local adaptation and "internal" forces representing constraints of inheritance and development. Vavilov placed too much emphasis on internal constraints and downgraded the power of selection. But Western Darwinians have erred equally in practically ignoring (while acknowledging in theory) the limits placed on selection by structure and development what Vavilov and the older biologists would have called "laws of form."

I have really got it into my head to try to be United States Senator, and, if I could have your support, my chances would be reasonably good. But I know, and acknowledge, that you have as just claims to the place as I have; and therefore I cannot ask you to yield to me, if you are thinking of becoming a candidate, yourself. If, however, you are not, then I should like to be remembered affectionately by you; and also to have you make a mark for me with the Anti-Nebraska members down your way.
— Abraham Lincoln

To the University of Oxford I acknowledge no obligation; and she will as cheerfully renounce me for a son, as I am willing to disclaim her for a mother. I spent fourteen months at Magdalen College: they proved the fourteen months the most idle and unprofitable of my whole life.
