“Timidity can be as dangerous as rashness.”

“I say that if England takes due advantage of her insular position, and confines herself to her own affairs, and does not run into needless and rash disputes with other countries, there never was a time when she stood so free from danger of war as at the present moment.”

“Reading can be dangerous.”

“Daydreams can be dangerous.”

“[T]he North’s ideology glorifies the heart over the mind, instincts over consciousness, which makes rash decisions more likely to be made, even quite low down the military command structure. There is therefore a significant danger of some sort of limited clash at any time. But that has always been the case.”

“"Dangerous" does not mean exciting or bold; it means likely to cause great harm. The most dangerous idea is the only dangerous idea: The idea that ideas can be dangerous.”

“Dreams can be dangerous things.”

“And a third danger is timidity. Few men are willing to brave the disapproval of their fellows, the censure of their colleagues, the wrath of their society. Moral courage is a rarer commodity than bravery in battle or great intelligence. Yet it is the one essential, vital quality of those who seek to change a world which yields most painfully to change.”

“Damaged people are dangerous. They know they can survive.”

“Belief can be manipulated. Only knowledge is dangerous.”
