The single biggest problem in communication is the illusion that it has taken place.
George Bernard Shaw

A system of morality which is based on relative emotional values is a mere illusion, a thoroughly vulgar conception which has nothing sound in it and nothing true.
Socrates

There are as many pillows of illusion as flakes in a snow-storm. We wake from one dream into another dream.
Ralph Waldo Emerson

There is an optical illusion about every person we meet.
Ralph Waldo Emerson

Do not be misled by what you see around you, or be influenced by what you see. You live in a world which is a playground of illusion, full of false paths, false values and false ideals. But you are not part of that world.
Sai Baba

Illusion is the first of all pleasures.
Voltaire

Moody Blues
"Nights in white satin"

Nights in white satin, never reaching the end,
Letters I've written, never meaning to send.
Beauty I've always missed, with these eyes before.
Just what the truth is, I can't say anymore.

'Cos I love you, yes I love you, oh how I love you.

Gazing at people, some hand in hand,
Just what I'm going through they can't understand.
Some try to tell me, thoughts they cannot defend,
Just what you want to be, you will be in the end.

And I love you, yes I love you,
Oh how I love you, oh how I love you.

Nights in white satin, never reaching the end,
Letters I've written, never meaning to send.
Beauty I've always missed, with these eyes before.
Just what the truth is, I can't say anymore.

'Cos I love you, yes I love you,
Oh how I love you, oh how I love you.
'Cos I love you, yes I love you,
Oh how I love you, oh how I love you.

"Late Lament"

Breathe deep the gathering gloom,
Watch lights fade from every room.
Bedsitter people look back and lament,
Another day's useless energy spent.

Impassioned lovers wrestle as one,
Lonely man cries for love and has none.
New mother picks up and suckles her son,
Senior citizens wish they were young.

Cold hearted orb that rules the night,
Removes the colours from our sight.
Red is grey and yellow white.
But we decide which is right.
And which is an illusion?
