Leonardo da Vinci and Charles Darwin. Leonardo "had the habit of conversing with himself in his writings and of putting his thoughts into the clearest and most simple form". He used "left-handed or mirror writing" (a technique described as "so characteristic of him") to protect his scientific research from other readers. The fear of persecution, social disgrace, and being proved incorrect are regarded as contributing factors to Darwin's delaying the publication of his radical and influential work On the Origin of Species. One of the results of controversies caused by a writer's work is scandal, which is a negative public reaction that causes damage to reputation and depends on public outrage. It has been said that it is possible to scandalise the public because the public "wants to be shocked in order to confirm its own sense of virtue". The scandal may be caused by what the writer wrote or by the style in which it was written. In either case, the content or the style is likely to have broken with tradition or expectation. Making such a departure may in fact, be part of the writer's intention or at least, part of the result of introducing innovations into the genre in which they are working. For example, novelist D H Lawrence challenged ideas of what was acceptable as well as what was expected in form. These may be regarded as literary scandals, just as, in a different way, are the scandals involving writers who mislead the public about their identity, such as Norma Khouri or Helen Darville who, in deceiving the public, are considered to have committed fraud. Writers may also cause the more usual type of scandal – whereby the public is outraged by the opinions, behaviour or life of the individual (an experience not limited to writers). Poet Paul Verlaine outraged society with his behaviour and treatment of his wife and child as well as his lover. Among the many writers whose writing or life was affected by scandals are Oscar Wilde, Lord Byron, Jean-Paul Sartre, Albert Camus, and H. G. Wells. One of the most famously scandalous writers was the Marquis de Sade who offended the public both by his writings and by his behaviour. Punishment The consequence of scandal for a writer may be censorship or discrediting of the work, or social ostracism of its creator. In some instances, punishment, persecution, or prison follow. The
