His most recent work,“Afterlives,”explores the generational effects of German colonialism in Tanzania, and how it divided communities.

Anders Olsson,the chair of the committee that awards the prize, said at the news conference on Thursday that Gurnah “is widely recognized as one of the world’s more pre-eminent post-colonial writers.”  

老师好！

2021年纽约时报刊摘的一篇文章中，诺贝尔文学奖主席Anders Olsson先生对时年文学诺奖得主Abdulrazak Gurnah的评价文字中使用了如下的结构“....one of the world’s more pre-eminent post-colonial writers .”

其中，使用了比较级而不是最高级，即one of the world’s most pre-eminent post-colonial writers，对此现象，我感到有点疑惑。

想请老师帮助辨析。

谢谢老师
