I believe that it is a metaphor because metaphors compare things without using the words like or as.
The psychotherapy that addresses "the whole person" is the so-called humanistic psychotherapy. Instead of trying to point fingers at specific problems in an individual's life, it assumes a holistic view, taking the person as a whole instead of focusing on their particular aspects. Its goal is to empower the individual and strengthen their belief in themselves, as well as other people.
According to; http://www.history-of-the-microscope.org/robert-hooke-microscope-history-micrographia.php
The Englishman Robert Hooke (18th July 1635 - 3rd March 1703) was an architect, natural philosopher and brilliant scientist, best known for his law of elasticity (Hooke's law), his book Micrographia, published in 1665 and for first applying the word "cell" to describe the basic unit of life. It is also less well known that there is substantial evidence that Hooke developed the spring watch escapement, independently of and some fifteen years before Huygens, who is credited for this invention. Hooke also is recognised for his work on gravity, and his work as an architect and surveyor.Tl;dr He was an architect and a great scientist and philosopher.
