The album title reflects the core concerns of the album's lyrics. It was originally intended to be split into two parts. According to
Ivar Bjørnson:'Axioma' "was from the basic form of Axiom in Latin, meaning self-evident truth. The whole process of natural universal truth, scientific truth contrasting to what Enslaved is doing which is very much about man-made truth. The starting point would be that everything is going on inside our heads." Grutle Kjellson explained that "The words Ethica Odini are the Latin translation of an
Old Norse poem called
Hávamál (Haavamaal) from 1655 I think, it can be translated into The Ethics Of Odin. It became a 3-word title actually by coincidence, Ethica Odini was supposed to be a sub-title, but the artist painted the words in a row. We saw at it and felt it looked better.""The poem and Ethica Odini are our biggest axiom. Old ethics, old wisdom, old advice on how to interact oneself with nature and other human beings. The common spirituality, so to speak. It's kind of a fist in the face of monotheistic thinking. We feel that a lot of the old thoughts written down in that poem are very much translatable to modern day life in 2010, and we have lost a lot of that type of reasonable thinking along the way through enduring centuries of monotheism."Musically the album is much heavier and more intense than band's previous few albums. "“Ethica Odini” simply explodes out of the gates with a ferocity we haven't heard since 2003's landmark
Below the Lights, a thunderous, mid-paced gallop with guitars sounding nearly as icy as they did on 1994's Frost. It's enough to take the listener aback after years of comparatively sedate tunes." The album is still highly progressive however, with wide-ranging influences, and unconventional, complex song structures.
AllMusic write that "Quieter passages, melodic arpeggios, contrast-giving keyboard parts, and
Herbrand Larsen's distinctive clean singing still populate most every track, but largely in secondary roles (the predominantly gentle "Night Sight" being the only notable exception); which doesn't mean they are any less impactful", and that "the "progressive" label still looms tall among the top three or four genre descriptions applicable to Enslaved's ever-complex and unpredictable sound (psychedelics not so much this time around), and the fact that black metal does too is all that longtime acolytes could ask from a band honorable enough to hang onto their musical roots while constantly intriguing and captivating them with new experiments." ==Reception==
