Context:Umqondo womlingo onzima nomlingo othambile waduma ngoSanderson wokwakha umhlaba nokwakha izinhlelo zemilingo ezindaweni eziqanjiwe. Igama elithi hard and soft lisuselwa ku-hard and soft sciences, elizivumela ngokwalo ekubhekeleni ku-hard science fiction kanye ne-soft science fiction. Zombili lezi zinkulumo ziyizindlela ezicishe zifane zokuchaza imikhawulo emibili ye-spectrum. Amasistimu omlingo aqinile alandela imithetho ethile, umlingo ulawulwa futhi uchazelwa umfundi ekulandiseni okuningiliziwe kwemishini ngemuva kwendlela umlingo 'osebenza' ngayo futhi ungasetshenziselwa ukwakha izilungiselelo ezizungeza uhlelo lomlingo. Amasistimu omlingo othambile angase angabi nemithetho noma imingcele echazwe ngokucacile, noma anganikeza ukwaziswa okulinganiselwe ngokusebenza kwawo. Zisetshenziselwa ukwakha umuzwa wokumangala kumfundi.
Umlingo onzima uhlale uvinjelwe ngokuqinile yisethi yemithetho engalingisa umhlaba ohleleke kakhudlwana kumfundi, kuyilapho umlingo othambile uma uguquguquka kakhudlwana, ungenayo imikhawulo echazwe ngokucacile futhi ungasetshenziswa ukufaka umuzwa wokumangala kumfundi.
