Experience teaches us that it is much easier to prevent an enemy from posting themselves than it is to dislodge them after they have got possession.
George Washington

Fear nothing but what thy industry may prevent; be confident of nothing but what fortune cannot defeat; it is no less folly to fear what is impossible to be avoided than to be secure when there is a possibility to be deprived.
Francis Quarles

First, we have to lower our costs to levels that are more competitive. This will prevent the lower-cost airlines from pushing us out of the markets we want to serve. We've made great progress on this front, but we need to keep pushing.
Gerard Arpey

For some years I have spent my time on exactly these questions - both in thinking about ways to prevent war, and in thinking about how to fight, survive, and terminate a war, should it occur.
Herman Kahn

Owen Arthur

God doesn't go to jail for the pound of weed you got caught going over the Laredo with - even though he apparently has the knowledge, power, and care to prevent it - you go to jail. God passes go and the courts collect two hundred dollars.
Stephen Evans

Elizabeth I

Guantanamo allows us to secure dangerous detainees without the risk of escape, while at the same time providing us with valuable intelligence information on how best to proceed in the war against terror and prevent future attacks.
Jim Ryun

He has no right to his life when his duty calls him to resign it. Other men are bound... to deprive him of life or liberty, if that should appear in any case to be indispensably necessary to prevent a greater evil.
William Godwin

He who does not prevent a crime when he can, encourages it.
Lucius Annaeus Seneca

Hence a ship is said to be tight, when her planks are so compact and solid as to prevent the entrance of the water in which she is immersed: and a cask is called tight, when the staves are so close that none of the liquid contained therein can issue through or between them.
William Falconer

How prone poor Humanity is to dam up the minutest remnants of its freedom, and build an artificial roof to prevent it looking up to the clear blue sky.
E. T. A. Hoffmann

I am convinced that military action will not prevent further acts of international terrorism against the United States.
Barbara Lee

I am responsible. Although I may not be able to prevent the worst from happening, I am responsible for my attitude toward the inevitable misfortunes that darken life.
Walter Anderson

I decry the current tendency to seek patents on algorithms. There are better ways to earn a living than to prevent other people from making use of one's contributions to computer science.
Donald Knuth

I did what I did not to make money but to help prevent the defeat of a new system which had, at great cost, given ordinary people food and fares which they could afford, a good education and a health service.
Melita Norwood

I don't need arms, and neither does anyone else... At the very least, a ban would prevent fights from turning deadly.
Luiz Inacio Lula da Silva

I don't try to describe the future. I try to prevent it.
Ray Bradbury

I have argued above that we cannot prevent the Singularity, that its coming is an inevitable consequence of the humans' natural competitiveness and the possibilities inherent in technology.
Vernor Vinge

I have read many studies out of the Karolinska Institute in Sweden and they demonstrated that Vitamin E, Co-Q-10, and Fish Oil could protect the immune system of athletes and prevent disease.
