While the words carry somewhat different connotations in different contexts, conservation, preservation and reconstruction are not exchangeable terms, not in any part of life. In socio-cultural context, conservation seeks the static and to inhibit natural processes. Preservation protects and safeguards things that otherwise would be corrupted or would eventually disappear, but lets it live its natural life, while reconstruction will always be different to the original it seeks to reconstruct and more commonly than not is, in form, heavily influenced by contemporary ideals and not ideals of the time of its origin.
A bit of a pretentious knobhead with thoughts too big for his head and a need to get them out to leave room for other things.
