I realise that in this undertaking I place myself in a certain opposition to views widely held concerning the mathematical infinite and to opinions frequently defended on the nature of numbers.

I've probably understood men too well. I realise they are predatory by nature and I have a certain acceptance of the male animal.

We are more than just flesh and bones. There's a certain spiritual nature and something of the mind that we can't measure. We can't find it. With all our sophisticated equipment we cannot monitor or define it and yet it's there.

Humans have certain properties and characteristics which are intrinsic to them just as every other organism does. That's human nature.

Although our intellect always longs for clarity and certainty our nature often finds uncertainty fascinating.

There is a certain enthusiasm in liberty that makes human nature rise above itself in acts of bravery and heroism.

Economic medicine that was previously meted out by the cupful has recently been dispensed by the barrel. These once unthinkable dosages will almost certainly bring on unwelcome after-effects. Their precise nature is anyone's guess though one likely consequence is an onslaught of inflation.

There are certain pursuits which if not wholly poetic and true do at least suggest a nobler and finer relation to nature than we know. The keeping of bees for instance.

Swans sing before they die - 'twere no bad thing should certain persons die before they sing.

I'm really an inner spirit that only makes itself known through the music. A lot of people think I'm an introvert or quiet and moody. I've even heard some people say that there's a certain mystery or darkness about me. I'm not that way. I'm just really into what I do.

I think Lady Gaga is great and is changing pop music and bringing back a certain rock 'n' roll spirit swagger to the game.

Great music is in a sense serene it is certain of the values it asserts.

There are certain pieces of music that are always attached to certain books.

I am quite certain in my heart of hearts that modern music and modern art is not a conspiracy but is a form of truth and integrity for those who practise it honestly decently and with all their being.

Beyond a certain point the music isn't mine anymore. It's yours.

All that stuff about heavy metal and hard rock I don't subscribe to any of that. It's all just music. I mean the heavy metal from the '70s sounds nothing like the stuff from the '80s and that sounds nothing like the stuff from the '90s. Who's to say what is and isn't a certain type of music?

There are certain things in which mediocrity is not to be endured such as poetry music painting public speaking.

There are certain sounds that I've found work well in nearly any context. Their function is not so much musical as spatial: they define the edges of the territory of the music.

Music in itself carries a whole set of messages which are very very rich and complex and the words either serve to exclude certain ones or point up certain others.

I've studied various schools of thought... I acknowledge that some Muslims consider music prohibited but I've found a lot of evidence from the life of the Prophet to show that he allowed certainly but even encouraged music at certain times.

All that stuff about heavy metal and hard rock I don't subscribe to any of that. It's all just music. I mean the heavy metal from the Seventies sounds nothing like the stuff from the Eighties and that sounds nothing like the stuff from the Nineties. Who's to say what is and isn't a certain type of music?

I'm not terribly happy about rock and roll. Certain rock music is uninspiring numbing it makes you feel like an idiot.

Certainly tolerance and acceptance were at the forefront of my music.

I'll give up this sort of touring madness certainly but music-everything is based on music. No I'll never stop my music.
