That's an intresting question. In the general context, I would say my thoughts on this subject are based on how 'building' affects the human person.
We can see from various and simplistic shapes that humans are affected in one way or another based on what they 'precieve' or 'see' in relation to themselves.
We can see that some people are greatly attracted to circular items, whereas other people are detracted from square shaped items.
We know, from ingrained social dogma, that rectangular items invoke the sense of 'money' or 'prosperity' and circular items invoke the sense of 'perpetuity' or 'unity'.
Given this we can look at 'buildings' or modern architecture, let's say in a large city. By simply looking downtown, we can see various types of buildings, from basic square buildings, to the more complex angular buildings. Some of these buildings project a persona of being foreful, such as a bank; or being helpful, such as the flowing curves and waves of a hospital. From being whimsical, thus being angular, to being spiritual, thus being sharply steeped.
In general, i would say my thoughts on architecture is that, having a firm understanding of how shapes interact with each other, and how the overall picture feels to the human staring at it, is the fundamental idea behind design.
Given this we can say that people, espeically those within huge cities, or metro areas, are exposed to many types of mixed signals daily. Each person being influanced by what they see, and what is around them ever so much more than the person who doesn't live within these 'architectual megalithic sites'. One could almost say that those not exposed to such a multitude of shapes and designs is more 'simplistic' than one who is exposed to these 'imposing structures'.
Now, if you are asking what are my thoughts on architecture in regards to actually building a system; then i would have to say that: A system is a complex interaction of events and issues resolved to form a single and/or multiple outcome. Architecture helps us resolve this system by giving us a means to 'map' the many interactions and events that make up the overal outcome.
Hope that helped :)
