Just as in the microcosm there are seven `windows' in the head (two nostrils, two eyes, two ears, and a mouth), so in the macrocosm God has placed two beneficent stars (Jupiter, Venus), two maleficent stars (Mars, Saturn), two luminaries (sun and moon), and one indifferent star (Mercury). The seven days of the week follow from these. Finally, since ancient times the alchemists had made each of the seven metals correspond to one of the planets; gold to the sun, silver to the moon, copper to Venus, quicksilver to Mercury, iron to Mars, tin to Jupiter, lead to Saturn.

From these and many other similar phenomena of nature such as the seven metals, etc., which it were tedious to enumerate, we gather that the number of planets is necessarily seven... Besides, the Jews and other ancient nations as well as modern Europeans, have adopted the division of the week into seven days, and have named them from the seven planets; now if we increase the number of planets, this whole system falls to the ground... Moreover, the satellites are invisible to the naked eye and therefore can have no influence on the earth, and therefore would be useless, and therefore do not exist.

Don't go West young man. (Advice to Columbus.)
I. A Voyage to Asia would require three years.
II. The western Ocean is infinite and perhaps unnavigable.
III. If he reached the Antipodes he could not get back.
IV There are no Antipodes because the greater part of the globe is covered with water, and because St. Augustine said so.
V. Of the five zones, only three are habitable.
VI. So many centuries after the Creation, it is unlikely that anyone could find hitherto unknown lands of any value.

Men might as well project a voyage to the Moon as attempt to employ steam navigation against the stormy North Atlantic Ocean.

This `telephone' has too many shortcomings to be seriously considered as a practical form of communication. The device is inherently of no value to us.

While theoretically and technically television may be feasible, commercially and financially I consider it an impossibility, a development of which we need waste little time dreaming.

[Television] won't be able to hold on to any market it captures after the first six months. People will soon get tired of staring at a plywood box every night.
