"To his [ Plato's ] great disappointment, he found Anaxagoras adducing simple physical reasons, instead of the teleological reasons, which he had expected. Such a teacher could no longer allure him."

All good things require effort. That which is worth having will cost part of your physical being, your intellectual power, and your soul power—‘Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you.’ (Matt. 7:7.) But you have to seek, you have to knock. On the other hand, sin thrusts itself upon you. It walks beside you, it tempts you, it entices, it allures. You do not have to put forth effort. … Evil seeks you, and it requires effort and fortitude to combat it. But truth and wisdom are gained only by seeking, by prayer, and by effort.
