Responses to the logical problem can be grouped into several families, each with its own advantages and disadvantages. “Social” trinitarians defend an account of the Trinity on which the Father, Son, and Spirit are three distinct centers of consciousness, with three distinct centers of knowledge, will, and action, who nevertheless count as a single God. Social trinitarians attempt to secure the divine unity by arguing that a single divine nature can support three separate consciousnesses. They may also claim that the three persons necessarily love each other so perfectly and act in such harmony that they are properly regarded as a single God. Prominent social trinitarians include Richard Swinburne (1994), William Lane Craig (2006), Keith Yandell (2009), and William Hasker (2013).
