Where the change is too great, or where an organ has been modified cumulatively in some one direction, until it has reached a development too seriously out of harmony with the habits of the organism taken collectively, then the organism holds itself excused from further effort, throws up the whole concern, and takes refuge in the liquidation and reconstruction of death.
"Luck or Cunning?"
Samuel Butler
The unlimited educational opportunity of health boards consists in their privilege to point out repeatedly and cumulatively the industrial and community benefits that result from habits of health, and the industrial and community losses that result from habits of unhealthy living.
"Civics and Health"
William H. Allen
If then we accept the conclusion that the effects of individual experience are not cumulatively hereditary we shall cease to cavil at the fact that there has been no anatomical or structural progress in the human body or brain since the time when men first became social and civilised beings, that is to say, since they first began to work together with their heads and hands, and we shall see that that which was to be expected has always happened, in that, from the earliest historical times to the present day, human life has been as the rolling and unrolling of a carpet.
