Never undertake anything for which you wouldn't have the courage to ask the blessings of heaven.
Georg C. LichtenbergThe natural scientists of the previous age knew less than we do and believed they were very close to the goal: we have taken very great steps in its direction and now discover we are still very far away from it. With the most rational philosophers an increase in their knowledge is always attended by an increased conviction of their ignorance.
Georg C. LichtenbergThe noble simplicity in the works of nature only too often originates in the noble shortsightedness of him who observes it.
