This is a long quote, but for me it represents everything I love about Russian literature: the expression of an important philosophical idea in beautiful language.
From War and Peace by Leo Tolstoy
"The question that had perturbed Pierre on the Mozhaysk hill and all that day now seemed to him quite clear and completely solved. He now understood the whole meaning and importance of this war and of the impending battle. All he had seen that day, all the significant and stern expressions on the faces he had seen in passing, were lit up for him by a new light. He understood that latent heat (as they say in physics) of patriotism which was present in all these men he had seen, and this explained to him why they all prepared for death calmly, and as it were lightheartedly.
"Not take prisoners," Prince Andrew continued: "That by itself would quite change the whole war and make it less cruel. As it is we have played at war- that's what's vile! We play at magnanimity and all that stuff. Such magnanimity and sensibility are like the magnanimity and sensibility of a lady who faints when she sees a calf being killed: she is so kind-hearted that she can't look at blood, but enjoys eating the calf served up with sauce. They talk to us of the rules of war, of chivalry, of flags of truce, of mercy to the unfortunate and so on. It's all rubbish! I saw chivalry and flags of truce in 1805; they humbugged us and we humbugged them. They plunder other people's houses, issue false paper money, and worst of all they kill my children and my father, and then talk of rules of war and magnanimity to foes! Take no prisoners, but kill and be killed! He who has come to this as I have through the same sufferings..."
Prince Andrew, who had thought it was all the same to him whether or not Moscow was taken as Smolensk had been, was suddenly checked in his speech by an unexpected cramp in his throat. He paced up and down a few times in silence, but his eyes glittered feverishly and his lips quivered as he began speaking.
"If there was none of this magnanimity in war, we should go to war only when it was worth while going to certain death, as now. Then there would not be war because Paul Ivanovich had offended Michael Ivanovich. And when there was a war, like this one, it would be war! And then the determination of the troops would be quite different. Then all these Westphalians and Hessians whom Napoleon is leading would not follow him into Russia, and we should not go to fight in Austria and Prussia without knowing why. War is not courtesy but the most horrible thing in life; and we ought to understand that and not play at war. We ought to accept this terrible necessity sternly and seriously. It all lies in that: get rid of falsehood and let war be war and not a game. As it is now, war is the favorite pastime of the idle and frivolous. The military calling is the most highly honored.
"But what is war? What is needed for success in warfare? What are the habits of the military? The aim of war is murder; the methods of war are spying, treachery, and their encouragement, the ruin of a country's inhabitants, robbing them or stealing to provision the army, and fraud and falsehood termed military craft. The habits of the military class are the absence of freedom, that is, discipline, idleness, ignorance, cruelty, debauchery, and drunkenness. And in spite of all this it is the highest class, respected by everyone. All the kings, except the Chinese, wear military uniforms, and he who kills most people receives the highest rewards.
"They meet, as we shall meet tomorrow, to murder one another; they kill and maim tens of thousands, and then have thanksgiving services for having killed so many people (they even exaggerate the number), and they announce a victory, supposing that the more people they have killed the greater their achievement. How does God above look at them and hear them?" exclaimed Prince Andrew in a shrill, piercing voice. "Ah, my friend, it has of late become hard for me to live. I see that I have begun to understand too much. And it doesn't do for man to taste of the tree of knowledge of good and evil.... Ah, well, it's not for long!" he added."
