Physical Form
In the ancient past there were varying levels of belief in a flat Earth, with the Mesopotamian culture portraying the world as a flat disk afloat in an ocean. The spherical form of the Earth was suggested by early Greek philosophers; a belief espoused by Pythagoras. By the Middle Ages—as evidenced by thinkers such as Thomas Aquinas—European belief in a spherical Earth was widespread. Prior to circumnavigation of the planet and the introduction of space flight, belief in a spherical Earth was based on observations of the secondary effects of the Earth's shape and parallels drawn with the shape of other planets.

Famous quotes containing the words physical and/or form:
“Nationality is the miracle of political independence; race is the principle of physical analogy.”
—Benjamin Disraeli (1804–1881)
“Fantasy is a product of thought, Imagination of sensibility. If the thinking, discursive mind turns to speculation, the result is Fantasy; if, however, the sensitive, intuitive mind turns to speculation, the result is Imagination. Fantasy may be visionary, but it is cold and logical. Imagination is sensuous and instinctive. Both have form, but the form of Fantasy is analogous to Exposition, that of Imagination to Narrative.”
—Sir Herbert Read (1893–1968)
