Jeg har opdaget en farlig flertydighed i sproget mht. implikationer. Betragt disse to s\u00e6tninger:<\/p>\n

S1. P implicerer ikke-Q. [P \u2192\u00acQ]<\/p>\n

S2. P implicerer ikke Q. [\u00ac(P \u2192Q)]<\/p>\n

Disse er meget forskellige. Det kan ses p\u00e5 deres forskellighed i sandhedstabellen:<\/p>\n\n<\/col>\n<\/col>\n<\/col>\n<\/col>\n<\/col>\n<\/col>\n\n\n\n\n\n\n

I tale kan det v\u00e6re sv\u00e6rt at h\u00f8re forskel. Derfor anbefales det, at man bruger ‘det er ikke tilf\u00e6ldet at…’ eller ‘det er falsk at…’ i stedet for at placere et ‘ikke’ efter implicerer i s\u00e6tninger lign. S2:<\/p>\n
