Power tends to corrupt and absolute power corrupts absolutely.

The science of politics is the one science that is deposited by the streams of history, like the grains of gold in the sand of a river and the knowledge of the past, the record of truths revealed by experience, is eminently practical, as an instrument of action and a power that goes to making the future.

Power corrupts, and absolute power corrupts absolutely.

Power tends to corrupt and absolute power corrupts absolutely.

And remember, where you have a concentration of power in a few hands, all too frequently men with the mentality of gangsters get control. History has proven that.
