This article considers the role of theory in the development of communication as a field of inquiry. Arguing that the relationship between the parts and whole of the field has not been adequately understood, it suggests that embracing a fuller understanding of communication's singularity might work better for both communication scholars and those situated in other fields of inquiry.Time complicates the appraisal of theory development in a field of study like communication. Unlike more traditional disciplines that have been entrenched for longer than individual members can remember, communication's development provides an uneven backdrop on which the activities of current members rest. Its unevenness is exacerbated by the field's temporal newness, where the relationship between the field's parts and its imagined whole remains out of sync. Rather than provide a reliable landscape on which theory might develop in more or less predictable ways, the theoretical horizon associated with communication has had other effects: It has created unchallenged and often unarticulated coalitions, lent stature to mythical giants while marginalizing their more diminutive neighbors, linked known scholars in automatic ways to otherwise abstract research agendas and challenged academic identities still in formation. With time's passage always subject to simultaneous pathways of opportunity and diminution, depending on who is reflecting, appraising the development of theory in conjunction with a platform like Communication Theory depends ultimately on the circumstances and identities of those engaging in its appraisal.The time span of 25 years is significant for me because I received my doctorate at just about the point that Communication Theory launched. The field of communication was then primed for a growth spurt, supported largely by both the so-called end of the "Cold War" and the explosion of the digital revolution. Making efforts at rapprochement timely, by opening the East-West master narrative to an increasingly vocal North-South distinction, and rendering aspects of communication-its devices, effects, and institutions-more widely and differently relevant than they had been, these developments helped orient the field upward and outward, as measured by its premier scholarly association, the International Communication Association: In
