"In solving a problem of this sort, the grand thing is to be able to reason
backwards. That is a very useful accomplishment, and a
very easy one, but people do not practise it much. In the every-day affairs
of life it is more useful to reason forwards, and so
the other comes to be neglected. There are fifty who can reason
synthetically for one who can reason analytically." - Sherlock
Holmes
