We must not listen to those who advise us 'being men to think human thoughts, and being mortal to think mortal thoughts' but must put on immortality as much as possible and strain every nerve to live according to that best part of us, which, being small in bulk, yet much more in its power and honour surpasses all else.

Those whose days are consumed in the low pursuits of avarice, or the gaudy frivolties of fashion, unobservant of nature's lovelinessof demarcation, nor on which side thereof an intermediate form should lie.

Whatsoever that be within us that feels, thinks, desires, and animates, is something celestial, divine, and, consequently, imperishable.

To Unlearn is as hard as to Learn

Nothing is what rocks dream about

A likely impossibility is always preferable to an unconvincing possibility.

Something is infinite if, taking it quantity by quantity, we can always take something outside.
