Architecture is the embodiment of the arts and sciences, a complex combination which results in an ambiguous whole. What once was just a means of shelter, has evolved into a means of which to communicate and express the ever evolving necessities of contemporary society. The demands of the people coupled with the zeitgeist of the period, more often than not, precipitate a prevailing architectural style, one with which the architects of the period rally to. Two centuries apart, Étienne-Louis Boullée and Louis Kahn, through their tireless re-examination of the discipline, have established profound ideologies on the nature of architecture, which remarkably allude to common principles.
