KhORIQA (arabai- az odat berun, gayrioddi), guftori gayrioddi va noravshanest, ki durusti yo nodurustii onro muayyan namudan mushkil ast. Xoriqa odatan ba afkori umum, aqoidi mamul va hatto ba aqli solim muvofiqat namekunad. Dar mantiq muhokimaero, ki tavassuti on du khulosai yakdigarro istisnokunanda barmeoyad va isboti har dui onho imkonpazir ast, Xoriqa yo antinomiya guyand. Chunin natijaho na rostu na durugand.
Dar vaqtash mutafakkironi Yunoni Qadim ba in masala tavajjuh zohir karda budand. Taqriban dar okh. a. 19 badi ba vujud omadani nazariyai majmuho olimon Khoriqaro baroi halli masalahoi gunoguni matematiki istifoda meburdand. S. 1895 G. Kantor, pas az du sol Burali-Forti novobasta az yakdigar Khoriqaro kashf kardand.
Khoriqai digare, ki onro s. 1902—03 olimi anglis B. Rassel oshkor namudaast ba majmui hamai majmuhoe, ki unsuri khud shuda nametavonad, vobasta ast. Matematik va mantiqshinosi mashhuri muosir S. Klini takid namudaast, ki az paydoishi ilmi mantiqi matematiqi ziyoda az nim asr guzashta boshad ham, to hol yagon halli durusti Khoriqaro paydo kardan mumkin nest. Lekin chunin holat manoi ba inkishofi ilm tanho tasiri manfi rasondani Khoriaqaro nadorad. Zero Xoriqa nazariyahoro goho shubhanok megardonad va dar inkishofu takmili nazariya, mantiqu matematika naqshi muayyan dorad. N. Sayfulloev.
