I have resolved to describe all the animals of the world, and to do so in a way that is both accurate and comprehensive, so that future generations may benefit from my labors.

The study of nature is the study of God's handiwork, and therefore a most noble and pious pursuit.

It is not enough to simply observe animals; we must also dissect them, and examine their internal structures, if we are to truly understand them.

Many things are written about animals that are false, and based on superstition rather than truth. It is my aim to correct these errors.

The diversity of life on Earth is astonishing, and far greater than anyone has yet imagined.

We should not be afraid to question the authority of ancient writers, for even the greatest among them can make mistakes.

The true scientist must be a polymath, skilled in many disciplines, for nature does not divide itself into neat categories.

It is a great pity that so many rare and wonderful creatures are unknown to us, simply because we have not taken the trouble to seek them out.

The study of languages is essential for the natural historian, for many important observations are hidden in foreign tongues.

I have included in this work not only animals known to me, but also those described by others, even if I have not seen them myself, for the sake of completeness.

The classification of animals is a difficult task, and one that is constantly evolving as new knowledge comes to light.

It is better to admit ignorance than to invent falsehoods.

The natural world is full of wonders, both great and small, and all deserve our attention.

I have endeavored to present the facts as I find them, without prejudice or preconceived notions.

The true measure of a scholar is not how much he knows, but how much he is willing to learn.

The pursuit of knowledge is a never-ending journey, and each discovery opens the door to new questions.

It is a shame that so many people are content to remain ignorant of the natural world around them.

The study of animals can teach us much about ourselves, and our place in the grand scheme of creation.

I have included illustrations in this work, for a picture is often worth a thousand words, especially when describing unfamiliar creatures.

The natural world is a vast library, and we have only just begun to read its pages.
