1. In Logic and Philosophy it is said that synthesis is the following
    1. The action of proceeding in thought from causes to effects, or from laws or principles to their consequences. E17.
    2. In Kantian philosophy, the action of the understanding in combining and unifying isolated sense-data into a cognizable whole. E19.
    3. In Hegelian philosophy, the final stage of a dialectic progression in which an idea is proposed (thesis), then negated (antithesis), and finally transcended by a new idea that resolves the conflict between the first and its negation. L19.
  2. More generally synthesis may be understood as the following: The action or an act of putting together parts or elements to make up a complex whole; the combination of immaterial or abstract things, or of elements into an ideal or abstract whole; the state of being so put together. Also, a complex whole made up of a number of united parts or elements. M19.
