How do freethinkers find purpose and meaning in life?

Freethinkers have come to the stark realization that the universe is completely indifferent to any of the wants and needs of the human intellect. Strangely, if you give serious thought to this situation you'll understand that it provides us with the greatest amount of hope possible in assigning purpose and meaning to our lives. We, alone, are in control of our happiness and, conversely, our despair. To proclaim, instead, that an all-powerful god personally intervenes in our affairs is not only self-centered and arrogant but it's also an excuse to evade personal responsibility. Freethinkers know that purpose is arrived at through honest inquiry and that meaning is determined by the importance we assign to something. An ultimate goal is happiness. The attainment of happiness is best accomplished by helping others to achieve their best.
