I strive to see the world with fresh eyes, to question everything.

The pursuit of knowledge is a journey without end.

My heart is forever bound to the wild and untamed places of the earth.

The noblest and most important result of the study of nature is to arrive at a general conception of the universe.

Everything is interaction and reciprocal influence.

The true measure of a nation's wealth is its intellectual capital.

The great object of my present journey is to collect facts, to observe, to measure, and to compare.

Nature, in her most varied forms, is always beautiful.

The cultivation of the earth is the most important of all human occupations.

The human mind is never so active as when it is engaged in the contemplation of nature.

Everywhere, the earth is covered with a carpet of vegetation, which varies in its character according to the climate and the soil.

The most important thing in life is to learn to give out love, and to let it come in.

The unity of nature, the connection of all phenomena, is the great truth which I have endeavored to establish.
