Suppose you are working on an article that you plan on sending to some good journal with a high rejection rate. You know that what you have written still needs some work, but you submit it anyway in the hope of a conditional acceptance and comments with the help of which you will perfect your piece. This is a mistaken approach. Never submit anything that is not as good as you can make it. And this for a reason supplied long ago by that master observer of the human condition, Baltasar Gracian (1601-1658):
Never show half-finished things to others. Let them be enjoyed in their perfection. All beginnings are formless, and what lingers is the image of that deformity. The memory of having seen something imperfect spoils out enjoyment when it is finished. To take in a large object at a single glance keeps us from appreciating the parts, but it satisfies our taste. Before it is, everything is not, and when it begins to be, it is still very close to nonbeing. It is revolting to watch even the most succulent dish being cooked. Great teachers are careful not to let their works be seen in embryo. Learn from nature, and don't show them until they look good. (The Art of Worldly Wisdom #231, tr. Christopher Maurer.)
