Model building is the art of selecting those aspects of a process that are relevant to the question being asked. As with any art, this selection is guided by taste, elegance, and metaphor; it is a matter of induction, rather than deduction. High science depends on this art.

The relevance of Marxism to science is that it removes it from its imagined position of complete detachment and shows it as a part, but a critically important part, of economy and social development.

John Desmond Bernal

Of all the ways of acquiring books, writing them oneself is regarded as the most praiseworthy method. Writers are really people who write books not because they are poor, but because they are dissatisfied with the books which they could buy but do not like.

Walter Benjamin

I am only an average man but, by George, I work harder at it than the average man.

Theodore Roosevelt

Any serious shift towards more sustainable societies has to include gender equality.

Helen Clark

I wish I was as cocksure of anything as Tom Macaulay is of everything.

Lord Melbourne

In a movie like this, the relationship between the two guys is crucial. It sinks or swims on how these two guys are together. I think we did a good job.

Eddie Murphy

I have always had good strength in my legs from working out with weights. I have also been riding a bike of some sort for most of my life and have good agility.

Mark-Paul Gosselaar

Welcome to fear, said Moist to himself. It's hope, turned inside out. You know it can't go wrong, you're sure it can't go wrong...But it might.

Terry Pratchett

Do a little bit more than average and from that point on our progress multiplies itself out of all proportion to the effort put in.

Paul J. Meyer

Man becomes man only by his intelligence, but he is man only by his heart.

Henri Frederic Amiel

Individuals who want to believe that there is no fulfillment in love, that true love does not exist, cling to these assumptions because this despair is actually easier to face than the reality that love is a real fact of life but is absent from their lives.

Bell Hooks

To be now a sensible man, by and by a fool, and presently abeast!

William Shakespeare
