“I'll tell you truly: I value my thought and work terribly, but in essence - think about it - this whole world of ours is just a bit of mildew that grew over a tiny planet. And we think we can have something great - thoughts, deeds! They're all grains of sand”

“Just think! This whole world of ours is only a speck of mildew sprung up on a tiny planet, yet we think we can have something great - thoughts,, actions! They are all but grains of sand”

“I do value my work awfully; but in reality only consider this: all this world of ours is nothing but a speck of mildew, which has grown up on a tiny planet. And for us to suppose we can have something great - ideas, work - it's all dust and ashes.”

“All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, until they take root in our personal experience.”

“Sometimes we have thoughts that even we don't understand. Thoughts that aren't even true—that aren't really how we feel—but they're running through our heads anyway because they're interesting to think about.”

“And it is a fact an absolute fact that there are creatures on the surface of this earth that have never been studied by man . . . There are other worls - worlds within this world - that we can only begin to imagine. We may think we have seen all that there is to be seen on this tiny planet of ours. We most certainly have not - and perhaps never shall.”
