True scientific progress is achieved not by mere accumulation of facts, but by the continuous refinement of theories and models.

I think we have been through a period where too many people have been given to understand that if they have a problem, it's the government's job to cope with it. 'I have a problem, I'll get a grant.' 'I'm homeless, the government must house me.' They're casting their problem on society. And, you know, there is no such thing as society. There are individual men and women, and there are families. And no government can do anything except through people, and people must look to themselves first. It's our duty to look after ourselves and then, also to look after our neighbour. People have got the entitlements too much in mind, without the obligations.

True leadership is about making tough decisions for the greater good.

We are all travelers in the wilderness of this world, and the best we can find in our travels is an honest friend.
