If we keep raising carbon dioxide levels, we may not be able to think straight anymore. At a thousand parts per million (which is within the realm of possibility for 2100), human cognitive ability falls 21 percent. "The largest effects were seen for Crisis Response, Information Usage, and Strategy,” a Harvard study reported, which is too bad, as those skills are what we seem to need most.

Robert A. Heinlein
The bread which you hold back belongs to the hungry; the coat, which you guard in your locked storage-chests, belongs to the naked; the footwear mouldering in your closet belongs to those without shoes. The silver that you keep hidden in a safe place belongs to the one in need. Thus, however many are those whom you could have provided for, so many are those whom you wrong.
Basil of Caesarea
We need to be careful not to harbour any resentment against those who harm us, but rather to pray for them with love. Whatever any of our fellow men does, we should never think evil of him. We need always to have thoughts of love and always to think good of others. Look at Saint Stephen the first martyr. He prayed, Lord, do not hold this sin against them. We need to do the same.
Porphyrios of Kafsokalyvia
Should you encounter the enemy, he will be defeated! No quarter will be given! Prisoners will not be taken! Whoever falls into your hands is forfeited. Just as a thousand years ago the Huns under their King Attila made a name for themselves, one that even today makes them seem mighty in history and legend, may the name German be affirmed by you in such a way in China that no Chinese will ever again dare to look cross-eyed at a German.
Wilhelm II of Germany
I am always afraid of explaining what I am doing, because my mind works so perversely. If I know why I am doing something it immediately goes to another channel and I try not to do that anymore. So in any interview there is a possibility that I have to leave the interview and change my entire life. I think I'll stop now and let the works answer the questions. To much information is an obstacle to seeing. My works are created to be seen.
