“Although we may not be able to mark the precise boundary beyond which organic beings do not appear, it is certain that in all geological epochs, subsequent, at least, to that of the primary rocks, animals and plants have existed in successive families; they have been created, have lived their day, and by the operation of physical causes, have perished; while new races have been called into being, and in their turn have ceased to be, in order to give room to other families, requiring, perhaps, a different climate, and a new order of things.”

“Whatever may have been the causes which have operated in the past, and are operating now, to draw the people into the cities, those causes may all be summed up as "attractions "”

Ebenezer Howard (1850–1928) British writer, founder of the garden city movement

Introduction.
Garden Cities of To-morrow (1898)
Context: Whatever may have been the causes which have operated in the past, and are operating now, to draw the people into the cities, those causes may all be summed up as "attractions "; and it is obvious, therefore, that no remedy can possibly be effective which will not present to the people, or at least to considerable portions of them, greater "attractions " than our cities now possess, so that the force of the old "attractions" shall be overcome by the force of new "attractions" which are to be created. Each city may be regarded as a magnet, each person as a needle; and, so viewed, it is at once seen that nothing short of the discovery of a method for constructing magnets of yet greater power than our cities possess can be effective for redistributing the population in a spontaneous and healthy manner.
