When people talk of the freedom of writing, speaking or thinking I cannot choose but laugh. No such thing ever existed. No such thing now exists; but I hope it will exist. But it must be hundreds of years after you and I shall write and speak no more.

~ John Adams

I must study politics and war that my sons may have liberty to study mathematics and philosophy.
