"Hellenistic" is a modern word and a 19th-century concept; the idea of a Hellenistic period did not exist in Ancient Greece. Although words related in form or meaning, e.g. Hellenist (Ancient Greek: , Hellenistes), have been attested since ancient times, it was J. G. Droysen in the mid-19th century, who in his classic work Geschichte des Hellenismus, i.e. History of Hellenism, coined the term Hellenistic to refer to and define the period when Greek culture spread in the non-Greek world after Alexander's conquest. Following Droysen, Hellenistic and related terms, e.g. Hellenism, have been widely used in various contexts; a notable such use is in Culture and Anarchy by Matthew Arnold, where Hellenism is used in contrast with Hebraism.

Logical empiricism (also logical positivism or neopositivism) was an early 20th-century attempt to synthesize the essential ideas of British empiricism (e.g. a strong emphasis on sensory experience as the basis for knowledge) with certain insights from mathematical logic that had been developed by Gottlob Frege and Ludwig Wittgenstein. Some of the key figures in this movement were Otto Neurath, Moritz Schlick and the rest of the Vienna Circle, along with A.J. Ayer, Rudolf Carnap and Hans Reichenbach.

Spielberg's films often deal with several recurring themes. Most of his films deal with ordinary characters searching for or coming in contact with extraordinary beings or finding themselves in extraordinary circumstances. In an AFI interview in August 2000 Spielberg commented on his interest in the possibility of extra terrestrial life and how it has influenced some of his films. Spielberg described himself as feeling like an alien during childhood, and his interest came from his father, a science fiction fan, and his opinion that aliens would not travel light years for conquest, but instead curiosity and sharing of knowledge.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why does Spielberg think aliens would visit?
Ah, so..
curiosity and sharing of knowledge
