During my school days I had a teacher who never gave anyone full marks. He maintained that to do so would imply that the pupil's work was perfect, whereas nothing is or ever can be perfect.
Is it true that perfection is unattainable? The material senses, which maintain that life and intelligence are in matter, insist that it is. These senses testify to a man born into a physical body and a material world—a mortal subject for a term to the tyrannical forces of evil, to sin and sickness, who is believed to enter eternal life by dying.
But this picture of man presents an illusion having no more substance than a desert mirage. Furthermore, the senses themselves are as false as their evidence, since matter is mindless. They are mesmeric, hypnotizing the human being into believing that his body and environment are material and subject to both an evil and a good power over which he has little control. And even though, for some, high standards may be the aim, perfection is always the last thing to be expected.
