It is true that impatience, the mother of stupidity, praises brevity, as if such persons had not life long enough to serve them to acquire a complete knowledge of one single subject, such as the human body; and then they want to comprehend the mind of God in which the universe is included, weighing it minutely and mincing it into infinite parts, as if they had to dissect it!

Where the mind is without fear and the head is held high Where knowledge is free.

The foundation of our Empire was not laid in the gloomy age of Ignorance and Superstition, but at an Epoch when the rights of mankind were better understood and more clearly defined than at any former period, the researches of the human mind, after social happiness, have been carried to a great extent, the Treasures of knowledge, acquired by the labours of Philosophers, Sages and Legislatures, through a long succession of years, are laid open for our use, and their collected wisdom may be happily applied in the Establishment of our forms of Government.

There comes a time when the mind takes a higher plane of knowledge but can never prove how it got there.

Iron rusts from disuse; water loses its purity from stagnation... even so does inaction sap the vigor of the mind.
