Be ye lamps unto yourselves.

Be your own reliance.

Hold to the truth within yourselves

as to the only lamp.

BUDDHA

True words always seem paradoxical but no other form of teaching can take its place.

Lao-Tse

Who then are the true philosophers?
Those who are lovers of the vision of truth.

PLATO

My people are destroyed by the lack of knowledge;

because thou hast rejected knowledge 

I will also reject thee.

Hosea

If the way which, as I have shown, leads hither seems very difficult, it can nevertheless be found. It must indeed be difficult since it is so seldom discovered; for if salvation lay ready to hand and could be discovered without great labour, how could it be possible that it should be neglected almost by everybody? But all noble things are as difficult as they are rare.
