It is a matter of tacit consensus that rationalist adeptness in urban planning traces its foundations to the philosophy of the Renaissance thinker and mathematician René Descartes. This study suggests, in turn, that the planned urban environment of the Renaissance may have also led Descartes, and his intellectual peers, to tenets that became the foundations of modern philosophy and science. The geometric street pattern of the late middle ages and the Renaissance, the planned townscapes, street views and the formal garden (...) design, appeared as parables for the perfection of the universe and the supremacy of critical reason. It is within this urban metaphor that Descartes's philosophical narrative betrays perceptual and conceptual impact from the contrast between convoluted medieval townscapes and the emerging harmonious street patterns where defined vistas and predictable clarity of street views were paramount. The geometrically delineated street views of the Renaissance new town became the spark that lit the philosopher's sagacity in reflecting upon the concept of "clear and distinct ideas." Past suggestions that Descartes was led to his philosophical breakthroughs through his discovery of co-ordinate geometry reinforce further the stance that Renaissance planning predisposed rationalist thought.

Discussions of green design and sustainable architecture have become common in the architectural profession, but not in philosophy. This is unfortunate, as philosophers could make important contributions to this discussion, given that these terms rife with ambiguities and that the relationships between these ideas and the traditional Vitruvian values of architecture (beauty, structure, and utility) are unclear. In a recent article, Tom Spector addresses some of these issues to assess whether the notion of sustainability could underpin an entire design philosophy. (...) He concludes that it cannot. I argue that Spector’s argumentsare flawed. After discussing the history of green design, I connect a number of theories in the new field of environmental aesthetics to the question of architectural aesthetics to show how sustainability might inform architecture.
