Metaphors for ideas

An idea or theory is like a building or structure. Developing an idea is like building something, and destroying an idea is like destroying a building. For example:

  • It was a carefully constructed theory.
  • She completely demolished his argument.
  • The theory collapsed/fell apart after he produced new data.

An idea is also like a plant. Developing an idea is like helping a plant to grow, e.g.:



  • The idea grew in her mind until she could think of nothing else.
  • I had sown the seeds of doubt.
  • This belief quickly took root.
  • It was a fruitful line of research.
