Quotations of the Month
Proclaim Liberty throughout all the Land
unto all the Inhabitants Thereof
The Liberty Bell
(from Leviticus 25:10)
They that can give up
essential liberty
to obtain a little temporary safety
deserve neither liberty nor safety.
Benjamin Franklin, 1755
They had a year of joy, twelve months of the strange heaven which the salmon know on beds of river shingle, under the gin-clear water. ... Looking back on it, ... they did not remember that in this year it had ever rained or frozen.
-- The Ill-Made Knight (Ch. 14, p. 381)
[A description of the Republican Party that has not become obsolescent.]
To the Editor:
After six years of the Bush administration and seven addresses by President Bush to Congress on the state of the union, it's now clear that Mr. Bush's political philosophy can be condensed into two principles:
First, most domestic problems in the United States can be solved by tax cuts or tax credits.
Second, most of the United States' foreign problems can be solved by wars or threats of war. ...
--Anthony J. DiStefano, Aiken, S.C., Jan. 24, 2007
--The New York Times, January 25, 2007
The notion that this bill doesn't keep people out of foreclosure is true. It doesn't combat global warming. It doesn't get troops out of Iraq. It won't help me lose weight. There are a lot of things this bill won't do that I very much want to do. None of them are a reason to vote against a bill that doesn't do what it doesn't say it's going to do but does what it does. What it does is go to the aid of cities that have been victimized.
-- Rep. Barney Frank, answering a criticism of a housing bill he supports.
-- "A Liberal Wit Builds Bridges To the G.O.P.", New York Times, May 13, 2008.
Economics 101
Tax exemptions for privileged groups brought high taxes on industry and agriculture, and emigration increased.
- -- Article on Charles II of Spain, The Columbia Encyclopedia, 5th ed., 1993.
