- "Careful users maintain the distinction between inhuman and inhumane. Inhumane, the opposite of humane, means 'lacking in compassion or kindness; cruel; not merciful': inhumane treatment. Inhuman, the opposite of human, is stronger and has a wider scope than inhumane. To be inhuman means to lack all human qualities, not only compassion and kindness: inhuman violence, inhuman living conditions. Inhuman has the additional meaning of 'not having human form': An inhuman shape appeared at the window."
(Martin Manser, Good Word Guide, 7th ed. Bloomsbury, 2011)
- "Inhuman and inhumane overlap in meaning to such an extent that it is impossible to sustain a distinction in their use. In general, inhuman refers to the characteristic of a person or action, whereas inhumane considers the same characteristic rather more in relation to the effect or the consequences of the action on the sufferer."
