Mr. Haldane's Daedalus has set forth an attractive picture of the future as it may become through the use of scientific discoveries to promote human happiness. Much as I should like to agree with his forecast a long experience of statesmen and governments has made me somewhat sceptical. I am compelled to fear that science will be used to promote the power of dominant groups rather than to make men happy. Icarus having been taught to fly by his father Daedalus was destroyed by his rashness. I fear that the same fate may overtake the populations whom modern men of science have taught to fly.
