(I became educated to the fact that the greatest pain does not come zooming down from a distant planet, but from the depths of the heart. Of course, both could happen; your wife and child could leave you, and you could be sitting alone in your empty house with nothing to live for, and in addition the Martians could bore through the roof and get you.)

菲利普·迪克（Philip K. Dick）在“对我们有些东西对我们的tempunauts”中，探讨了最深刻的认识，即最深切的痛苦通常是由于个人损失和情感动荡而不是外部威胁而引起的。这句话反映了内心的痛苦能力，表明诸如失去亲人之类的个人困难甚至可以抑制最梦幻般的恐惧，例如外星人的入侵。
