A great man does not seek applause or place; he seeks for truth; he seeks the road to happiness, and what he ascertains, he gives to others.

If a patient became sugar-free and blood sugar normal on a basal requirement diet, the caloric intake was gradually increased until sugar appeared in the urine. The tolerance was thus ascertained.

Mma Ramotswe had listened to a World Service broadcast on her radio one day which had simply taken her breath away. It was about philosophers who called themselves existentialists and who, as far as Mma Ramotswe could ascertain, lived in France. These French people said that you should just live in a way which made you feel real, and that the real thing to do was the right thing too. Mma Ramotswe had listened in astonishment. You did not have to go to France to meet existentialists, she reflected; there were many existentialists right here in Botswana. Note Mokoti, for example. She had been married to an existentialist herself, without even knowing it. Note, that selfish man who never once put himself out for another--not even for his wife--would have approved of existentialists, and they of him. It was very existentialist, perhaps, to go out to bars every night while your pregnant wife stayed at home, and even more existentialist to go off with girls--young existentialist girls--you met in bars. It was a good life being an existentialist, although not too good for all the other, nonexistentialist people around one.

I tell you as well as myself: what we see with our own eyes is nothing other than a cloud concealing what we should perceive with our inner sight, while what we listen to with our ears is merely a ringing sound disturbing what we should understand with our hearts. When we see a man being taken to prion by a police officer let us not hasten to assume he is a wrong-doer. When we see a corpse, and a man standing beside it with bloodstained hands, let us not conclude that this is a victim and his assassin. When we hear one man singing and another lamenting, let us ascertain which one of the two is truly happy.

Science has fulfilled her function when she has ascertained and enunciated truth.
