First edition. "It can not be repeated too often, that all designs from the mind consist of two distinct parts, divisible, and infinite. For example, Invention and Science, and the diversity of our opinions on the same subject, often comes from the side that we know best, regarded as the unique aspect; experience has taught me that architecture had almost always been treated and judged in separate parts, I conceived the idea of presenting it as a whole, seeking to make it understood, by from the outset using the best examples, that it is essentially a work of Sentiment, Engineering, and Taste, based on moral and physical values; directed by fixed and universally accepted qualities and natural principles; composed of simple elements, compounds, varied and reasoned, and finally understood by universal sentiment for which, ultimately, we must recognize that all things are created" (Introduction).
