Seven World Riddles
Emil du Bois-Reymond used ignoramus et ignorabimus in discussing what he called seven "world riddles", in a famous 1880 speech before the Berlin Academy of Sciences.
He outlined seven "world riddles", of which three, he declared, neither science nor philosophy could ever explain, because they are "transcendent". Of the riddles, he considered the following transcendental and declared of them ignoramus et ignorabimus: "1. the ultimate nature of matter and force, 2. the origin of motion,... 5. the origin of simple sensations, a quite transcendent question." However, depending on the interpretation of "ultimate nature" and "origin," it is possible to consider some of these as partially or completely solved. For example, the sensory systems for the traditional senses (sight, hearing, taste, smell, touch) are now mostly understood, including some of the associated neural processing.

Famous quotes containing the words world and/or riddles:
“Having children can smooth the relationship, too. Mother and daughter are now equals. That is hard to imagine, even harder to accept, for among other things, it means realizing that your own mother felt this way, too—unsure of herself, weak in the knees, terrified about what in the world to do with you. It means accepting that she was tired, inept, sometimes stupid; that she, too, sat in the dark at 2:00 A.M. with a child shrieking across the hall and no clue to the child’s trouble.”
—Anna Quindlen (20th century)
“Of all the riddles of a married life, said my father ... there is not one that has more intricacies in it than this—that from the very moment the mistress of the house is brought to [child]bed, every female in it ... becomes an inch taller for it....
I think rather, replied my uncle Toby, that ‘tis we who sink an inch lower.”
—Laurence Sterne (1713–1768)
