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?

Enlightenment is man's release from his self-incurred tutelage. Tutelage is man's inability to make use of his understanding without direction from another. Self-incurred is this tutelage when its cause lies not in lack of reason but in lack of resolution and courage to use it without direction from another. Sapere aude! 'Have courage to use your own reason!'- that is the motto of enlightenment.

Reason must know the heart's reasons and every other reason
Leonora CarringtonAt times to be silent is to lie. You will win because you have enough brute force. But you will not convince. For to convince you need to persuade. And in order to persuade you would need what you lack: Reason and Right

In our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence. A wise man, therefore, proportions his belief to the evidence.

Do not think that we say that these things are only to be received by faith, but also that they are to be asserted by reason. For indeed it is not safe to commit these things to bare faith without reason, since assuredly truth cannot be without reason.

Lovers and madmen have such seething brains,
Such shaping fantasies, that apprehend
More than cool reason ever comprehends.
The lunatic, the lover and the poet
Are of imagination all compact:
One sees more devils than vast hell can hold,
That is, the madman: the lover, all as frantic,
Sees Helen's beauty in a brow of Egypt:
The poet's eye, in fine frenzy rolling,
Doth glance from heaven to earth, from earth to heaven;
And as imagination bodies forth
The forms of things unknown, the poet's pen
Turns them to shapes and gives to airy nothing
A local habitation and a name.

Somebody must trespass on the taboos of modern nationalism, in the interests of human reason. Business can't. Diplomacy won't. It has to be people like us.

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.
