Thought for the day....

I know this is contradicting my own description of this blog.....but can you really think architecture? What is architecture if without a tangible manifestation of the thoughts that generate it? If it remains in the realm of thought alone....it cannot be architecture as it remains in mind space and does not get translated into physical space.
So what about all these thinkers who claim to be architects too...are they really architects? or are they just thinkers and no more? Should the ability to actually create tangible architecture be a critirion for the "architect"? Or just the ability to think space would suffice?
Food for thought........
