weak-minded

It was flat and pointed, like the heads of many of those unfortunates whom people imprison in asylums for the weak-minded.

They terrify the weak minded by frightful ideas which they hold out to them of the Deity.

The weak-minded baby will not do this, and often as late as two years it will not make any attempt to walk or to talk.

But how could this weak-minded sovereign co-operate with plebeians against the orders which sustained his throne?

A home where everything is done to promote their health and happiness is, for the weak-minded, a new world.

What madness to let a weak-nerved, weak-minded fellow like that go prowling about country roads in the night.
