as completely excluded as it is from the garden.

At the same time, the obstacles to the full development of the
capacities of the colonists by other conditions of the state of nature
than those already mentioned, would be removed by the creation of
artificial conditions of existence of a more favourable character:
Protection against extremes of heat and cold would [19] be afforded by
houses and clothing; drainage and irrigation works would antagonise
the effects of excessive rain and excessive drought; roads, bridges,
canals, carriages, and ships would overcome the natural obstacles to
locomotion and transport; mechanical engines would supplement the
natural strength of men and of their draught animals; hygienic
precautions would check, or remove, the natural causes of disease.
With every step of this progress in civilization, the colonists would
become more and more independent of the state of nature; more and
more, their lives would be conditioned by a state of art. In order to
attain his ends, the administrator would have to avail himself of the
courage, industry, and co-operative intelligence of the settlers; and
it is plain that the interest of the community would be best served by
increasing the proportion of persons who possess such qualities, and
diminishing that of persons devoid of them. In other words, by
selection directed towards an ideal.

Thus the administrator might look to the establishment of an earthly
paradise, a true garden of Eden, in which all things should work
together towards the well-being of the gardeners: within which the
cosmic process, the coarse struggle for existence of the state of
nature, should be abolished; in which that state should be replaced by
a state of art; [20] where every plant and every lower animal should
be adapted to human wants, and would perish if human supervision and
