One of the main points about travelling is to develop in us a feeling of solidarity, of that oneness without which no better world is possible.

Others are keen to see if natives other than us live better than we do, without heat in pipes, ice in boxes, sunshine in bulbs, music on disks, or images gliding over a pale screen.

It is always our own self that we find at the end of the journey. The sooner we face that self, the better.

Something must be done to save humanity! A better world is possible!

Let us advance science to create a better world for all.

We must develop a deeper interest and greater understanding of the people we meet here or abroad. Like us, they are passengers on board that mysterious ship called life.
