Crusades"},"content":{"rendered":"<p><span style=\"font-weight: 400\">A movement is \u201ca course or series of actions and endeavours on the part of a group of people working towards a shared goal; an organization, coalition, or alliance of people working to advance a shared political, social, or artistic objective\u201d<\/span> <span style=\"font-weight: 400\">(<\/span><i><span style=\"font-weight: 400\">Oxford English Dictionary<\/span><\/i><span style=\"font-weight: 400\">).<\/span><\/p>\n<p><span style=\"font-weight: 400\">A movement may lead to a campaign, \u201cany course of action analogous to a military campaign, either in having a distinct period of activity, or in being of the nature of a struggle, or of an organized attempt aiming at a definite result\u201d.<\/span><\/p>\n<p><span style=\"font-weight: 400\">And a campaign can develop into a crusade, \u201can aggressive movement or enterprise against some public evil, or some institution or class of persons considered as evil\u201d or harmful; or contrariwise, one might add, on behalf of some action perceived to be beneficial, ignoring the harm it might cause. This happens when campaigners become so convinced that their cause is right that they will not brook opposition. There can be no debate. What they want must be enacted, whatever the damage to others. Indeed, so convinced are they that only either benefits or harms will accrue, that they cannot conceive of any other outcome. The partition separating campaign from crusade is fragile.<\/span><\/p>\n<p><span style=\"font-weight: 400\">A supposed IndoEuropean root CRUC notionally meant to go back and forth; to cruise is to do just that, crossing from here to there. A Latin derivative, crux, originally described a rough wooden frame on which prisoners were exposed to die, often shaped as a cross, its structural elements going back and forth across each other. \u201cCrux\u201d therefore came to mean death on such a structure, and hence crucifixion. Mala crux, literally a bad cross, meant anything that causes annoyance or grief, such as a plague, and the phrase \u201ci in malam crucem\u201d meant, as we would say, \u201cgo hang yourself\u201d. Cruciare meant to torture someone or to inflict with pain or mental anguish. And cruciatus meant severe pain, pain that was excruciating. Crux then came to mean a sort of mental crossroads, posing difficulty in interpretation. It was then elevated to mean the chief problem or the main point of interest.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The cruciate ligaments in the knee cross each other. If you want to stitch the ends of a snapped tendon together you can use a stranded cruciate <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32684704\/\"><span style=\"font-weight: 400\">technique<\/span><\/a><span style=\"font-weight: 400\">, in which the strands, usually four or eight of them, criss-cross each other, locking the fibres together (Figure 1).<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-48548\" src=\"https:\/\/blogs.bmj.com\/bmj\/files\/2020\/09\/aronson_11sep.jpg\" alt=\"\" width=\"420\" height=\"192\" srcset=\"https:\/\/blogs.bmj.com\/bmj\/files\/2020\/09\/aronson_11sep.jpg 420w, https:\/\/blogs.bmj.com\/bmj\/files\/2020\/09\/aronson_11sep-300x137.jpg 300w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><\/p>\n<p><span style=\"font-weight: 400\">Another Latin word, crus, meant the lower leg or shin, typically when it was beaten or broken as a punishment, and by extension an upright support on a bridge. Crura are formations, generally in pairs, that look like a pair of legs, such as the crura cerebelli, crura cerebri, and crura diaphragmatis (Figure 2).<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-48546\" src=\"https:\/\/blogs.bmj.com\/bmj\/files\/2020\/09\/aronson11sep_2.jpg\" alt=\"\" width=\"665\" height=\"547\" srcset=\"https:\/\/blogs.bmj.com\/bmj\/files\/2020\/09\/aronson11sep_2.jpg 665w, https:\/\/blogs.bmj.com\/bmj\/files\/2020\/09\/aronson11sep_2-300x247.jpg 300w, https:\/\/blogs.bmj.com\/bmj\/files\/2020\/09\/aronson11sep_2-640x526.jpg 640w\" sizes=\"auto, (max-width: 665px) 100vw, 665px\" \/><\/p>\n<p><b>Figure 2<\/b><span style=\"font-weight: 400\">.

Its origin is obscure. That alchemists may have marked their pots with a cross to ward off the devil cannot be it\u2014the lamp came before the pot. Perhaps the lamp was hung behind the cross in church; or perhaps it had crossed wicks or four nozzles pointing in different directions. More likely, its name had nothing to do with crosses at all.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Crusades were <\/span><a href=\"https:\/\/www.historytoday.com\/archive\/feature\/crusades-complete-history\"><span style=\"font-weight: 400\">religious wars<\/span><\/a><span style=\"font-weight: 400\"> waged by such zealots as Peter the Hermit, King Louis VII of France, Frederick Barbarossa, and Richard the Lionheart in the 11<\/span><span style=\"font-weight: 400\">th<\/span><span style=\"font-weight: 400\">, 12<\/span><span style=\"font-weight: 400\">th<\/span><span style=\"font-weight: 400\">, and 13<\/span><span style=\"font-weight: 400\">th<\/span><span style=\"font-weight: 400\"> centuries to recover the Holy Land from the Muslims, eight largely fruitless major expeditions in all, with much collateral damage.

When EBM was introduced in the early 1990s it looked like a crusade, particularly in its espousal of hierarchies that favoured only randomized controlled trials and gave little credence to other forms of evidence. However, proponents of EBM now recognize that observational studies and even anecdotal reports have some value in particular circumstances. This is appropriate. EBM aims to encourage everyone to survey all the available evidence on both benefits and harms, and to decide where the balance lies, not to stress one and ignore the other.<\/span><\/p>\n<p><em><strong>Jeffrey Aronson<\/strong>\u00a0is a clinical pharmacologist, working in the Centre for Evidence Based Medicine in Oxford\u2019s Nuffield Department of Primary Care Health Sciences.
