The proper method for inquiring after the properties of things is to deduce them from experiments.
If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.
God made and governs the world invisibly, and has commanded us to love and worship him and no other God; to honor our parents and masters, and love our neighbours as ourselves; and to be temperate, just, and peaceable, and to be merciful even to brute beasts.
