Once a philosopher was traveling down a river in a small boat. While he 1_________________(cross) the river
(ask) the boatman:” You ever 3__________________
(hear) about Philosophy?” “No”, 4__________________
(say) the boatman. “I never 5_________________
(hear) about it. What it 6__________
(be)?” “I 7________________
(be) sorry for you, indeed,” replied the learned man, “you 8________________
(lose) a quarter of your life as it’s a very interesting science!” Several minutes later the philosopher asked the boatman another question: “You 9__________________
(hear) about Astronomy, when you 10_____________
(be) at school?” “No, I11_______________
(leave) school many years ago and I 12________________________
(forget) all about it.,” was the answer. To this the philosopher answered that he 13)__________________
(be) really sorry for the man, and he 14_________________
(think) that the boatman15_________________
(lose) a second quarter of his life.
Some minutes passed and the passenger again 16____________________(wonder) if the man ever 17__________________(hear) about Algebra. And the man 18______________(have to) admit that he never 19___________________(know) anything about it. “In that case you certainly 20_________________(lose) a third quarter of your life!” said the scientist.
At that very moment the boat struck on a big stone. The boatman jumped and cried: “You ever 21_______________(learn)22_________________(swim)?” “No,” was the answer. The boatman explained sadly to the philosopher that he 23_______________(be) sure the scientist 24________________(lose) his whole life as the boat 25________________________(sink).
