The problem is that it takes physicians so long to accept a radical change. And the lag is unacceptable.

For me, 'revolution' simply means radical change.

The advancement of all sciences, especially where there has been such a radical change, have been attended with persecution.

Youth should be radical. Youth should demand change in the world. Youth should not accept the old order if the world is to move on. But the old orders should not be moved easily -- certainly not at the mere whim or behest of youth. There must be clash and if youth hasn't enough force or fervor to produce the clash the world grows stale and stagnant and sour in decay.

The time draws near, when a radical change must take place for the whole world in the management of diplomacy.

The conservative who resists change is as valuable as the radical who proposes it.
