Aesthetics are rarely explicitly addressed in conjunction with ethics in the body of literature examining recent landscape architectural research. This seems strange given that, if ‘ecology’ is added to ‘aesthetics’ and ‘ethics’, the classic tripartite definition of the discipline is formulated, and most would agree that this constitutes the unique significance and substance of what we do. (…)

The apparent neglect of research that explicitly addresses aesthetics and ethics together may have several reasons. One aspect is that research paradigms, as well as conventions for working in professional practice, will typically narrow the focus and therefore the methodologies of study or practice. Though often challenged, such crude divisions appear to persist and obstruct the critical development of landscape architectural praxis at all levels. The integrative breadth of landscape architecture is hard to formulate within narrow research and disciplinary specialisms, so when these limitations are overcome landscape theory takes a leap forward. Another aspect contributing to the neglect of detailed aesthetic studies may be the lack of a tradition of philosophical discourse in landscape architecture, coupled with the fact that aesthetics as method, construct, practice, experience and the means toward critical judgment is notoriously hard to define with any rigor. The difficulty in both defining and conveying accurately the nature and significance of aesthetic experience, and in addition, the elusiveness of aesthetic judgment and its tendency to go with the flow of contemporary politics, social taste, and cultural transitions, often means that aesthetics are conveyed tangentially and metaphorically, and sometimes not at all. Many academics are deterred from such intangible topics and tacit approaches, especially the younger in the pursuit of PhDs to whom natural and social science appear to offer greater rigor because they are more amenable to explicit forms of knowledge.
