As a complement to one’s own personality, it is important for the philosopher to have a partner who is able to empathize and sense emotional effects while attending to the intellectual, logical connections. For the need for cognition, it is important to be able to make sense of all the necessary information and meaning. Everything that is expressed in an emotionally diffuse way is perceived as irrational. Also for the partnership it is good to be able to refer to reality. The philosopher needs clarity and truth.
