Concepts are the glue that holds our mental world together.Our concepts embody much of our knowledge of the world, telling us what things there are and what properties they have. It may not seem to be a great intellectual achievement to identify a bulldog or to know what to do with a tomato, but imagine what our lives would be like without such a conceptual ability. We might know the things we had experienced in the past—a particular chair, our bed, the breakfast we had today, our science teacher, etc.

Life On Mars
Named after the Roman god of war, Mars has been a source of continual fascination. It is one of our nearest neighbours in space, though it takes about a year to get there. It is very inhospitable with high winds racing across extremely cold deserts. But it is spectacular, with the highest volcano in the solar system and a giant chasm that dwarfs the Grand Canyon.
For centuries there has been fierce debate about whether there is life on Mars and from the 19th century it was even thought there might be a system of canals on the planet. This insatiable curiosity has been fuelled by writers like HG Wells and CS Lewis and countless sci-fi films about little green men.
So what do we know about Mars – its conditions, now and in the past? What is the evidence that there might be water and thus life on Mars? And when might we expect man to walk on its surface?
