Just got back from a pleasure trip: I took my mother-in-law to the airport.

In all private quarrels the duller nature is triumphant by reason of dullness.

I experience a period of frightening clarity in those moments when nature is so beautiful. I am no longer sure of myself, and the paintings appear as in a dream.

I need more sex, OK? Before I die I wanna taste everyone in the world.

America had often been discovered before Columbus, but it had always been hushed up.

It’s not a real adventure when you have to pay for it.

Our soul is cast into a body, where it finds number, time, dimension. Thereupon it reasons, and calls this nature necessity, and can believe nothing else.

Every particular in nature, a leaf, a drop, a crystal, a moment of time is related to the whole, and partakes of the perfection of the whole.

If you’re embarking around the world in a hot-air balloon, don’t forget the toilet paper.

A man who has not been in Italy, is always conscious of an inferiority.

A lot of people can’t stand touring but to me it’s like breathing. I do it because I’m driven to do it.

Mountains are the beginning and the end of all natural scenery.

There can never be any stop to learn about different cultures by travelling to different places. And whatever comes your way, continue the healthy eating habits.

People from all over the world come to London wanting to make their own mark on it, and they add to the energy and vitality of the capital. It’s got a bit busier since the ’60s, but the more the merrier!

A tramp, a gentleman, a poet, a dreamer, a lonely fellow, always hopeful of romance and adventure.

Take a course in good water and air; and in the eternal youth of Nature you may renew your own. Go quietly, alone; no harm will befall you.

You are a child of the sun, you come from the sun, and that is something true with the Earth also… your relationship with the Earth is so deep, and the Earth is in you and this is something not very difficult, much less difficult then philosophy.

You just feel a little odd when you don’t get your kind of food. Fortunately, there are Indian restaurants all over the world.

Nature abhors annihilation.

I love all kinds of insects, and I’ve heard Australia has some really interesting bugs.

I’ve been away since I was pretty much eight, traveling to the car tracks, and then going to Europe and traveling more.

I love Africa, and Ulusaba, our home in South Africa, is pretty special. It’s on a rocky hill overlooking the bush, and from your room, you can see lions stalking zebras by the waterhole.

I give the name of cosmic sense to the more or less confused affinity that binds us psychologically to the All which envelops us. The existence of this feeling is indubitable, and apparently as old as the beginning of thought… The cosmic sense must have been born as soon as man found himself facing the forest, the sea and the stars.

Both the man of science and the man of action live always at the edge of mystery, surrounded by it.

Even Hubble hasn’t found yet the end of this universe, and we don’t know that it has any end.

We cannot command Nature except by obeying her.

I think I mainly climb mountains because I get a great deal of enjoyment out of it. I never attempt to analyze these things too thoroughly, but I think that all mountaineers do get a great deal of satisfaction out of overcoming some challenge which they think is very difficult for them, or which perhaps may be a little dangerous.

New discoveries in science will continue to create a thousand new frontiers for those who still would adventure.

One can never know for sure what a deserted area looks like.

Flying might not be all plain sailing, but the fun of it is worth the price.

Touring is very routine. You get to the city, you go to the hotel, you got to be at the hotel by a certain time – it’s very routine. I’m not a very structured person, so when I get some structure, it’s cool; it’s good for me.

For the execution of the voyage to the Indies, I did not make use of intelligence, mathematics or maps.

Sponges grow in the ocean. That just kills me. I wonder how much deeper the ocean would be if that didn’t happen.

My absolute favourite piece of information is the fact that young sloths are so inept that they frequently grab their own arms and legs instead of tree limbs, and fall out of trees.

We sail within a vast sphere, ever drifting in uncertainty, driven from end to end.

What I’m trying to do is, is to make a significant difference in space flight. And help make space flight accessible to almost anyone.

There have been times that I’ve wept as I’ve gone from city to city and I’ve seen how far people have wandered from God.

Keep close to Nature’s heart… and break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.

Look deep into nature, and then you will understand everything better.

Climb the mountains and get their good tidings.

Death, like birth, is a secret of Nature.

We travel often to Asia, Africa, Europe, where they were born.

I have enjoyed great satisfaction from my climb of Everest and my trips to the poles. But there’s no doubt that my most worthwhile things have been the building of schools and medical clinics.

However, because Britain is young and exciting, I did show my second line here once or twice.

Man is but a reed, the most feeble thing in nature, but he is a thinking reed.
