With this in mind, look at the similarities and differences between Howard Roark and Frank Lloyd Wright with an eye to what is superficial and what is substantive. The real Frank Lloyd Wright ran his architectural firm like a medieval village, with himself as the lord and his apprentices as serfs. This is unlike the independent Roark, who respected genuine talent too much to work it that way or to accept the less competent. Roark's code of morality. From this beginning, it's easy to see that Roark would face personal and professional obstacles, so the story would have to enable these.
Architecture is unlike other professions in that it combines art and science.
However, shelter being vital to human survival and comfort, and it being the most expensive financial outlay for the majority of people, Roark's ingenuity has repercussions for all of society. Roark's need to feel aesthetic satisfaction toward his work synthesizes his art with his knowledge of science, and with it, unifies art and science as such in the book, and so too merges Roark's character with the two key aspects of his profession. For the reasons given by me above this comment, the comment itself is misdirected.
