"Contraceptive, there is a paradoxical, negative sense in which all possible future generation are the patients or subjects of a power wielded by those already alive...contraceptive simply... denied existences" (Lewis 55).

"Man's victory over Nature, we find the whole human race subjected to some individual men, and those individuals subjected... to their irrational impulses" (67).

Over the year, it seems like men wants to gain control over nature. The way, they go about this is through science. C.S Lewis is saying if what is natural gets completely eradicated by the unnatural, the world will be in disarray. First, the future generation would subjects the previous generation. The natural flow of thing will no longer exist because the naturals laws the governs men will be governed by men. Subsequently, the human population will be come subordinates to one man's desires. If the natural laws are gone the Tao will also cease to exist in people's lives. What would be left is The Abolition of Man. Without the Tao in man's life he will not know proper values and man will be left as illogical beings. Human king as it is known will no longer exist because everything will already be predetermined. Men will only be able do whatever the man wants him do. In conclusion, Lewis is saying that their are things in life that should be left a secret to men. Knowledge is not bad but with to much knowledge people start forgetting the principle of things. Then, they feel like they have exhibit the powers of a god or the God and takes control over nature.
