“I can see it, hear it, feel it, taste it - but I can never be on the inside of it with you. I cannot even be sure whether I really know what it is like. Is it 'like' my own? Or incomparable? Just as I can never know if what you see at any given moment is exactly the same as what I see. We look at a colour. We both call it red. But it is only because we have been taught to call it by that name. There is no guarantee - not ever - that we see it in the same way, that your red is my red.”

“You cannot see what I see because you see what you see. You cannot know what I know because you know what you know. What I see and what I know cannot be added to what you see and what you know because they are not of the same kind. Neither can it replace what you see and what you know, because that would be to replace you yourself.""Hang on, can I write this down?" said Arthur, excitedly fumbling in his pocket for a pencil.”

“I feel like you can look inside me and see all the places I am odd or unusual and fit your heart around them, for you are odd and unusual in just the same way. We are the same.”

“But you were only an idea to me before, an abstraction that lived in my mind and called forth its appropriate response. It was that abstraction I stabbed. But now, for the first time, I see you are a man like me. I thought of your hand-grenades, of your bayonet, of your rifle; now I see your wife and your face and our fellowship. Forgive me, comrade. We always see it too late. Why do they never tell us that you are poor devils like us, that your mothers are just as anxious as ours, and that we have the same fear of death, and the same dying and the same agony - Forgive me, comrade; how could you be my enemy? If we threw away these rifles and this uniform you could be my brother just like Kat and Albert. Take twenty years of my life, comrade, and stand up - take more, for I do not know what I can even attempt to do with it now.”

“As for all I can tell, the only difference is that what many see we call a real thing, and what only one sees we call a dream.”

“But just as we can all agree on what is red, even if we will never know if we each see it in the same way, so we can all agree - can’t we? - that no matter how confident we may appear to others, inside we are all sobbing, scared and uncertain for much of the time. Or perhaps it’s just me.Oh God, perhaps it really is just me.Actually it doesn’t really matter, when you come to think of it. If it is just me, then you are reading the story of some weird freak. You are free to treat this book like science fiction, fantasy or exotic travel literature. Are there really men like Stephen Fry on this planet? Goodness, how alien some people are. And if I am not alone, then neither are you, and hand in hand we can marvel together at the strangeness of the human condition.”
