Moths and other nocturnal insects navigate by the moon and stars. Those heavenly bodies are useful for them to find their way, even though they never get far from the surface of the earth. But lightbulbs and candles send them astray; they fly into the heat or the flame and die. For these creatures, to arrive is a calamity. When activists mistake heaven for some goal at which they must arrive, rather than an idea to navigate Earth by, they burn themselves out, or they set up a totalitarian utopia in which others are burned in the flames. Don't mistake a lightbulb for the moon, and don't believe that the moon is useless unless we land on it. After all those millennia of poetry about the moon, nothing was more prosaic than the guys in space suits stomping around on the moon with their flags and golf clubs thirty-something years ago. The moon is profound except when we land on it. Paradise
