All you have to do is decide what each aphorism is, find the right letter, assign it a number (A, K, U =1) and find the cache. 
Easy peasy. (and I've given you the "a"s and "the"s to make it easier.)
A) The A - - - - D - - - - - F - - - F - - F - - - the T - - -- (4th letter, second word - "the" is the first word)
B) N - - - - - - - - I- the M - - - - - O- I- - - - - - - - (3rd letter, first word)
C) B - - - - I - T - - - - - - T - - - W - - - - ( 3rd word, 5th letter)
D) I - F - - a P - - - -, I - F - - a P - - - - . ( last letter, 4th word)
E) E - - - - C - - - - H - - a S - - - - - L - - - - - ( 4th letter, 1st word)
F) A B - - - I - the H - - - I - W - - - - T - - I - the B - - - . ( 2nd letter, 8th word.)
G) Y - - C - - L - - - a H - - - - T - W - - - - B - - Y - - C - - - M - - - I - D - - - - . ( 3rd letter, 11th word)
