Consciousness and Self-Knowledge

One has no right to love or hate anything if one has not acquired a thorough knowledge of its nature. Great love springs from great knowledge of the beloved object, and if you know it but little you will be able to love it only a little or not at all.

All our knowledge has its origin in our perceptions.

The knowledge of all things is possible.

There are three classes of people: those who see. Those who see when they are shown. Those who do not see.

As every divided kingdom falls, so every mind divided between many studies confounds and saps itself.

The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.

One can have no smaller or greater mastery than mastery of oneself.
