More than a few years ago, I noticed that there were some email and blog taglines I really liked. In many cases, they were better than the message content.
With this in mind, I started collecting them in the form of a raw text tagline file. I chose raw text because I didn’t want to include any graphics, fancy typefaces or odd formatting. I wanted only the pithy and precise quotes.
This file has now grown to more than 1300 lines!
Some of it is obvious historical references with which I find kindred spirits. Many of Ben Franklin and Thomas Jefferson’s quotes, for example.
“An association of men who will not quarrel with one another is a thing which has never yet existed, from the greatest confederacy of nations down to a town meeting or a vestry.” – Thomas Jefferson
“A people that values its privileges above its principles will soon lose both.” – Thomas Jefferson
“A strong body makes the mind strong. As to the species of excercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball and others of that nature, are too violent for the body and stamp no moral character on the mind. Let your gun therefore be your constant companion of you walks.” – Thomas Jefferson to Peter Carr, 1785.
“Those who would give up Essential Liberty to purchase a little Temporary Safety, deserve neither Liberty nor Safety.” – Benjamin Franklin 1759
Then again, there are ancient gems from Roman times, such as:
“Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth.”
“it is possible for a man to live in a palace without wanting either guards or embroidered dresses, or torches and statues, and such-like show.”
“Life is all warfare and a stranger’s wanderings, and the reward is oblivion,”
“Do not waste what remains of your life in speculating about your neighbors… To wonder what so-and-so is doing and why, or what he is saying, or thinking, or scheming — in a word, anything that distracts you from fidelity to the ruler within you — means a loss of opportunity for some other task.” – Marcus Aurelius (121-180 AD)
I have many, many more from different ages up to the present.
What gems of great wisdom have you saved to share?

Not quite a tagline, but if you run one of my programs with –version, you get the version number, plus this quote.
“Few desire liberty; most wish only for a just master.”
— Sallust, as the Roman Republic became the Empire
