I am really dedicated to understanding the planet/creature on which we live and know that means I must go beneath the sea to see 72 percent of what is going on.

What drives me is exploration with a purpose, more the classic Royal Geographical Society genre.

So, you know, I think the age of exploration is just beginning, not ending, on our planet.

Most of the southern hemisphere is unexplored. We had more exploration ships down there during Captain Cook's time than now. It's amazing.

We often forget that everything we see, animate or inanimate, is a visual manifestation of the work of our invisible God. We have become so accustomed to trees, mountains, sky, air, water, flowers, animals, vegetables and people that we no longer see them for what they are - God's work.

He had a theory, Walt did, that the religious life, and all the agony that goes with it, is just something God sics on people who have the gall to accuse Him of having created an ugly world.

In America, we have always taken it as an article of faith that we 'battle' cancer; we attack it with knives, we poison it with chemotherapy or we blast it with radiation. If we are fortunate, we 'beat' the cancer. If not, we are posthumously praised for having 'succumbed after a long battle.'

I think that listening to music or creating music is a spiritual undertaking, so the process of creating music, you know, involves listening. It involves sensitivity, it involves humility, you know, and then also it's something which is higher than words.
