A hospital alone shows what war is.

At school nobody ever taught us how to light a cigarette in a storm of rain, nor how a fire could be made with wet wood-nor that it is best to stick a bayonet in the belly because there it doesn't get jammed, as it does in the ribs.

To forget is the secret of eternal youth. One grows old only through memory. There's much too little forgetting.

Kat and Kropp get in an argument over the war as they rest from an hour’s worth of drill (occasioned by Tjaden’s not saluting a major properly). Kat believes the war would be over if leaders gave all the participants “the same grub and the same pay,” as he says in a rhyme. Kropp believes the leaders of each country should fight each other in an arena to settle the war; the “wrong” people currently do the fighting.

Let the months and years come, they can take nothing from me, they can take nothing more. I am so alone, and so without hope that I can confront them without fear. The life that has borne me through these years is still in my hands and my eyes. Whether I have subdued it, I know not. But so long as it is there it will seek its own way out, heedless of the will that is within me." -All Quiet On The Western Front, Chapter 12

But probably that's the way of the world - when we have finally learned something we're too old to apply it - and so it goes, wave after wave, generation after generation. No one learns anything at all from anyone else.

The room shall speak, it must catch me up and hold me, I want to feel that I belong here, I want to hearken and know when I go back to the front line that the war will sink down, be drowned utterly in the great home-coming tide, know that it will then be past for ever, and not gnaw us continually, that it will have none but an outward power over us...Nothing stirs; listless and wretched, like a condemned man, I sit there and the past withdraws itself. And at the same time I fear to importune it too much, because I do not know what might happen then. I am a soldier, I must cling to that.
