There are two approaches to try to explain life: the direct study of life, then your analysis, and attempted explanation – or, the study of other attempted explanations, then your explanation of them.
(Either explore Africa for yourself, or write a critique of an essay on the life of Livingston.)
One word can bring enlightenment; two will bring delusion.
(The befuddling property of words, at least after the first one.)
The only one who may know what you want to know is the one who will not respond to your questions.
Why search for THE KNOWLEDGE when nothing could already be more intimate to you?
