The man without a purpose is a man who drifts at the mercy of random feelings or unidentified urges and is capable of any evil, because he is totally out of control of his own life. In order to be in control of your life, you have to have a purpose-a productive purpose.
Ayn RandEven if smog were a risk to human life, we must remember that life in nature, without technology, is wholesale death.
Ayn RandWhat I want you to understand, is the full evil of those who claim to have become convinced that this earth, by its nature, is a realm of malevolence where the good has no chance to win. Let them check their premises. Let them check their standards of value. Let them check - before they grant themselves the unspeakable license of evil-as-necessity - whether they know what is the good and what are the conditions it requires.
