“The gross and net result of it is that people who spent most of their natural lives riding iron bicycles over the rocky roadsteads of this parish get their personalities mixed up with the personalities of their bicycle as a result of the interchanging of the atoms of each of them and you would be surprised at the number of people in these parts who are nearly half people and half bicycles...when a man lets things go so far that he is more than half a bicycle, you will not see him so much because he spends a lot of his time leaning with one elbow on walls or standing propped by one foot at kerbstones.”

“Life is like riding a bicycle. You get nowhere standing up, so get up on that seat and go!”

“The question the doubter does not ask is whether faith was really useless or simply not used. What would you think of a boy who gave up learning to ride a bicycle, complaining that he hurt himself because his bicycle stopped moving so he had no choice but to fall off? If he wanted to sit comfortably while remaining stationary, he should not have chosen a bicycle but a chair. Similarly faith must be put to use, or it will become useless.”

“As one does a bear riding a bicycle. One sees it so rarely.(Spoken by Volger, on Deryn)”

“To ride a bicycle is in itself some protection against superstitious fears, since the bicycle is the product of pure reason applied to motion. Geometry at the service of man! Give me two spheres and a straight line and I will show you how far I can take them. Voltaire himself might have invented the bicycle, since it contributes so much to man’s welfare and nothing at all to his bane. Beneficial to the health, it emits no harmful fumes and permits only the most decorous speeds. How can a bicycle ever be an implement of harm?”

“When people recover from depression via psychotherapy, their attributions about recovery are likely to be different than those of people who have been treated with medication. Psychotherapy is a learning experience. Improvement is not produced by an external substance, but by changes within the person. It is like learning to read, write or ride a bicycle. Once you have learned, the skills stays with you. People no not become illiterate after they graduate from school, and if they get rusty at riding a bicycle, the skill can be acquired with relatively little practice. Furthermore, part of what a person might learn in therapy is to expect downturns in mood and to interpret them as a normal part of their life, rather than as an indication of an underlying disorder. This understanding, along with the skills that the person has learned for coping with negative moods and situations, can help to prevent a depressive relapse.”
