 From Julius Ceasar or from William Shakespeare?

"Beware the leader who bangs the drums of war in order to whip the citizenry into a patriotic fervor, for patriotism is indeed a double-edged sword. It both emboldens the blood, just as it narrows the mind. 

And when the drums of war have reached a fever pitch and the blood boils with hate and the mind has closed, the leader will have no need in seizing the rights of the citizenry. Rather, the citizenry, infused with fear and blinded by patriotism, will offer up all of their rights unto the leader and gladly so.

How do I know? For this is what I have done. And I am Caesar. "

Maybe from William Shakespeare and perhaps lifted from his play, Julius Caesar.

Words from Alexander Fraser Tytler (Lord-Woodhouseleeor) or from  Alexis de Toqueville?

"A democracy is always temporary in nature; it simply cannot exist as a permanent form of government. A democracy will continue to exist up until the time that voters discover that they can vote themselves generous gifts from the public treasury. From that moment on, the majority always votes for the candidates who promise the most benefits from the public treasury, with the result that every democracy will finally collapse due to loose fiscal policy, which is always followed by a dictatorship"

"The average age of the world's greatest civilisations from the beginning of history has been about 200 years. During those 200 years, these nations always progressed through the following sequence: 

From bondage to spiritual faith;
From spiritual faith to great courage;
From courage to liberty;
From liberty to abundance;
From abundance to selfishness;
From selfishness to complacency;
From complacency to apathy;
From apathy to dependence;
From dependence back into bondage."

Tytler’s theory set a cycle that every civilization goes through, which is drawn like this.
