A person who does not know the history of the last 3,000 years wanders in the darkness of ignorance, unable to make sense of the reality around him

If you don't know history, then you don't know anything. You are a leaf that doesn't know it is part of a tree.

The man who has no sense of history, is like a man who has no ears or eyes

There is properly no history; only biography.

Where history means nothing. Lessons are forgotten. Memories – of humanity, of all that is humane – are lost.

Professor Johnston often said that if you didn't know history, you didn't know anything. You were a leaf that didn't know it was part of a tree.

These individuals tend to be profoundly ignorant of the complex realities of the status quo, unconscious of their own ignorance, and ungrateful for what the past has bequeathed to them.

History has no meaning.

Those who don't know history are doomed to repeat it

The past is devoid of meaning like the present, and a refuge for cowards.

He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast.

A generation which ignores history has no past — and no future.

One should lie empty, open, choiceless as a beach — waiting for a gift from the sea.

As idle as a painted ship upon a painted ocean.
