The Beautiful has its place in speculative systems. The Beautiful has its place in speculative systems.

If you are unhappy, even the moon annoys you, sweet things taste bitter.

Everything about him is attractive.

I possess a more profound insight into the true nature of the higher mathematics than is generally supposed.

I do not think it is the function of the Analytical Engine to create music, but to develop and execute the operations necessary to this end when instructed to do so.

The machine is not a thinker, but a worker; it performs the operations it is directed to perform.

In the case of the Difference Engine, the entire table is calculated beforehand, and the results are then printed.

The cards which guide the Jacquard loom are analogous to the operation cards of the Analytical Engine.

The store is the memory of the machine, where variables and constants are kept.

The mill is the processing unit, where operations are performed.

The Analytical Engine consists of two parts: the store and the mill.

It is desirable to be able to work with numbers of any magnitude.

The engine can perform operations on symbols as well as on numbers.

The possibility of the machine's working with algebraic symbols suggests a wide field of application.

I wish you to reflect on the importance of this invention.

The science of harmony is an object which is susceptible of the most perfect combination of the truth and the reason.

My dear Babbage, I have worked very hard on your engine.

The diagrams are exceedingly useful; they classify the ideas in a most satisfactory manner.

I am sure that the Analytical Engine will be the wonder of the age.
