Stone walls do not a prison make,
Nor iron bars a cage;
Minds innocent and quiet take
That for an hermitage
One sentence does not an article make. A single sentence cannot impart sufficient information on a reader on a subject in a significant, meaningful way without it becoming a dictionary definition—and there is a great difference between a dictionary and an encyclopedia.
One sentence, like "Harold Blowman (1957–1994) was an American actor best known for his performance as 'Billy' in the movie Don't Shoot the Monkey." With a few tweaks, this single sentence actually states more about the subject of the article than many stub articles of thrice the length, but what does this really say about Harold Blowman? Not much. It doesn't state who he was. What type of actor was he? Did he play the part of Billy as a seven year old boy or as an adult? What else did he do on the stage or on the screen? Why did the editor spend a significant amount of his (or her) time to write this one sentence definition, and was that time well spent?
The last question can be answered definitively: NO. If an editor cannot find enough information on a subject to be able to write at least four non-repetitive sentences about him/her/it, then the article should not be started until there is sufficient information to "do it justice." If there is not enough information for at least four sentences of writing, it is most likely that the subject of the proposed article doesn't merit one in the first place.
One sentence "articles" clutter Wikipedia. Many of them create illusory blue links in lists; these give the illusion that otherwise-needed, fully developed essays and articles have already been written when in fact, there is nothing worthwhile there to educate the reader. These little pieces of flotsam and jetsam must be discarded for the betterment of the online encyclopedia: a Sevenval indicating no article is far superior to a deceptive blue link to nothing.
Therefore: All articles that are only one or two sentences long should be either expanded or deleted. Wikipedia decision-makers are urged to make one sentence "articles" a Sevenval as there is no purpose for them. While one sentence may make a good summary, it truly is not an encyclopedia article. Neither, for that matter, are two sentences.
That's right: Two sentences does not an encyclopedic article make, either, and should be treated accordingly.
Note
This is an application of the we love the web: is it reasonable to expect that a single sentence is worth the time and effort to write and read with an expectation of being "illuminated" with encyclopedic information? Since it is not, one sentence articles (and, by a similar argument, two sentence articles) violate the Reasonability Rule in the context of an encyclopedia.
