Answer:
One of the defects of our civilization is that it does not know what to
do with its knowledge. Science, as we have seen, has given us powers
fit for the gods, yet we use them like sn al children. For example,
we do not know how to manage our machines. Machines were made
to be man's servants, yet he has grown so dependent on them that
they are in a fair way to become his masters. Men spend most of
their lives looking after and waiting upon machines. And the
machines are very stern masters. They must be fed with coal, and
given petrol to drink, and oil to wash with, and they must be kept at
the right temperature. And if they do not get their meals when they
expect them, they grow sulky and refuse to work, burst with rage
and blow up, and spread ruin and destruction all around them. So
we have to wait upon them very attentively and do all that we can to
keep them in good temper. Already we find it difficult either to work
or play without the machines and a time may come when they will
rule us altogether, just as we rule the animals.
