The motion of the sun along the ecliptic is, of course, merely a reflection of the revolution of the earth around the sun, but the ancients believed the earth was fixed and the sun had and independent motion of its own, eastward among the stars. The glare of sunlight hides the stars in daytime, but the ancients were aware that the stars were up there even at night, and the slow eastward motion of the sun around the sky, at the rate of about thirty degrees each month, caused different stars to be visible at night at different times of the year.
The moon, revolving around the earth each month, also has an independent motion in the sky. The moon, however, changes it position relatively rapidly. Although it appears to rise and set each day, as does nearly everything else in the sky, we can see the moon changing position during as short an interval as an hour or so. The moon's path around the earth lies nearly in the same plane as the earth's path around the sun, so the moon is never seen very far from the ecliptic in the sky. There are five other objects visible to the naked eye that also appear to move in respect to the fixed background of stars on the celestial sphere. These are the planets Mercury, Venus, Mars, Jupiter, and Saturn. All of them revolve around the sun in nearly the same plane as the earth does, so they, like the moon, always appear near the ecliptic. Because we see the planets from the moving earth, however, they behave in a complicated way, with their apparent motions on the celestial sphere reflecting both their own independent motions around the sun and our motion as well.

Business is made up of people with all kinds of backgrounds, all kinds of motivations, and all kinds of tastes, just as in any other form. of human endeavour. Businessmen are not ambulatory balance' sheets and profit statements, but perfectly normal human beings, subject to whatever strengths, frailties, and limitations characterize man on the earth. They. are people grouped together in organizations designed to complement the weakness of one with strength of another, tempering the exuberance of the young with the caution of the more mature, the poetic soarings of one mind with the counting house realism of another. Any disfigurement which society may suffer will come from man himself, not from the particular vocation to which he devotes his time.
Any group of people necessarily represents an approach to a common denominator, and it is probably tree that even individually they tend to conform. somewhat to the general pattern. Many have pointed out the danger of engulfing our original thinkers in a tide of mediocrity. Conformity is not any more prevalent or any more exacting in the business field than it is in any other. It is a characteristic of all organizations of whatever nature. The fact is the large business unit provides greater opportunities for individuality and requires less in the way of conformity than other institutions of comparable size—the government, or the academic world, or certainly the military.
