Well, "admire" is usually a word we use for another person whom we revere and aspire to be like.
I have seen how the school encourages students to think beyond the tangibility of architecture to the intangible, philosophical, and theoretical form that defines the role of architects in our society.
I don't think this seems sincere. Any school with an architecture program will encourage students that way. So... the important thing is to figure out something meaningful to say. What is the real reason you would want to go to this school instead of a different one?
The best reason is when there is a particular prof whom you admire. So, you choose this school because of the prof whose articles/books have inspired you.
