For Fukuzawa, the government of the Korean Dynasties appeared to be totally against 'Equality' by discrimination by putting too much value on lineage and Keibatsu blood connection, Sinocentrism or petit Sinocentrism and disrespect for Japan as well as families repeating bloody strife over authority, no intention to be independent with their Sadaejuui policy and no consistency in their diplomacy; these things led him to write 'Datsu-A Ron' with his standpoint of 'ten wa hito no ue ni hito o tsukurazu...' (The heavens do not create Man above his station...) ("Gakumon no Susume" [An Encouragement of Learning]).
つまり、門閥、閨閥政治や中華思想また小中華思想など民族（人種）差別、日本蔑視思想で、「平等」の精神に真っ向から反する思想、親子（姑、嫁）が血みどろの権力闘争を繰り広げ、そのために事大主義に走り独立心がなく外交の一貫性がないこと、と福澤諭吉らから見れば、そう見える朝鮮王朝政府に対し、「天は人の上に人をつくらず...」（『学問のすゝめ』)とする思想を重んじる立場から「脱亜論」に至ったのだ、という解釈がある。
