it's not simply that the unexamined life is not worth living.
i'd actually argue that the unexamined life is not lived. we are reflective beings: we plan, we foresee, we anticipate. socrates was, of course, referring to contemplation that goes beyond the immediate to the more philosophical. all the same, it is fair to assume that all the members of our species are
involved in some degree of self-examination.
analysis of this kind is impossible without a little contextualization . . . that is, in thinking about the meaning and purpose of
my life, i must think about the meaning and purpose of life for my species, in general. anthrolopogy is both integral and quite natural. we all pursue it to varying degrees, often without noticing it. this is most often associated with the context of ethics, but it is equally visible when we strive for a promotion or for a date: we are simultaneously aware of a) what other members of our species
ought to find impressive and b) what they actually
do find impressive. (i'd love to discuss that discrepancy, but it's not really the subject of this diatribe!)
if i then come to believe that there is an entity who created this species, the character and intentions of that entity become important. if we call the entity "theos" and the study of its being "theology", then we can say that theology necessarily informs anthropology. which, as i've already argued, is essential to life. note: if theos exists, theology is significant *irrespective* of what it tells us about theos. whether we end up at deism or polytheism or whatever, the nature of the creator casts a shadow on the nature of man.
if people find that a partial history of theos' engagement with creation is recorded in a book, then theology must govern how that book is read - hermeneutics and bibliology.
if people organize into assemblies for worship, then theology must govern what they do when they are together - ecclesiology.
if people feel compelled to introduce others to theos, then theology must govern how they go about that task - soteriology, missiology, and homilitics.
various streams of theology - christology, pneumatology, hamartiology, eschatology, and so on - pertain specifically to the theos known as YHWH, but they are part of the essential theology of YHWH, and so necessarily inform the "practical" studies mentioned above.
maybe this seems really obvious . . . but we have to understand who YHWH is before we can understand who we are and how we are to engage with YWHW and one another.
