The Middle Ages focused obsessively on the old; our era is totally absorbed with the new. In medio stat virtus. In this short note, I advocate a strategy that blends copyright and copyleft for disseminating research results in the sciences. I argue that such a blend may be beneficial in fields such as mathematics and computer science, that it may facilitate the evolution and emergence of improved problem descriptions, whilst at the same time preserving author's rights, and easing researchers' work.

翻译：《中世纪》专注于旧时代;我们的时代完全被新时代所吸收。 在中世纪,我主张将版权和复制权混合起来用于传播科学研究成果的战略。我认为,这种混合在数学和计算机科学等领域可能是有益的,有助于改进问题描述的演变和出现,同时保护作者的权利,并放松研究人员的工作。
