The history behind architecture is basically founded upon the human need for shelter. Relatively, it is from this need though that the evolution of architectural development has become more successful in redefining the said option of structural establishment to be more of an expression that identifies with the being of the artist or the architect. The argument of Piranesi is more specifically related to the idea of defining architecture in a way that would specifically be based upon the traditional ways of structural establishment. On the other end, LeRoy tries to manifest a sense of distinction on what evolutionary architecture is about.
The liberty of architects to create is imposed by LeRoy to be the basis of what real architecture is about. Although there are particular base limitations such as the function that the structures ought to serve the society with, architects should be allowed to become artists at their own rights. Their desire to create something new in connection with their need to provide the society with shelter or a structural establishment where they could work or to function should not be hindered as this particular condition of creation is what makes the distinctive role of modern architecture is.
The world at present faces different challenging issues especially in relation to the condition of the environment and the capacity of the new developing systems of architecture to respond to such forms of complexities. Most often than not, it is the willingness of new generation architects to be more than what they are expected to be that allows them to create revolutionary operations that bring forth the possibility of creating establishments that were likely never been imagined to be possible of existing in the past. This way, architecture does not only take the role of establishing structures, but also the capacity to change the face of the world through such structures.
