Appearances are a glimpse of the obscure.

What one man can invent another can discover.

Most new discoveries are suddenly-seen things that were always there.

How gloriously legible are the constellations of the heavens!

Nature has planted in our minds an insatiable desire to seek the truth.

The eternal mystery of the world is its comprehensibility.

What one man can invent another can discover.

There are truths that prove their discoverers witless.

I am tormented with an everlasting itch for things remote. I love to sail forbidden seas and land on barbarous coasts.

The discovery of a new dish does more for human happiness than the discovery of a star.
