Some are born with knowledge, some derive it from study, and some acquire it only after a painful realization of their ignorance. But the knowledge being possessed, it comes to the same thing. Some study with a natural ease, some from a desire for advantages, and some by strenuous effort. But the achievement being made, it comes to the same thing.
I know, that since life is our most precious gift, and as far as we can be absolutely certain, it's given to us to live but once, let us so live we will not regret years of useless virtue, and inertia, and timidity, and ignorance, and in our last moments we can say: 'All my life, all my conscious energies, have been dedicated to the most noble cause in the world, the liberation of the human mind and spirit - beginning with my own'.
Wisdom leads to unity, but ignorance to separation.
So long as God seems to be outside and far away, there is ignorance.
But when God is realised within, that is true knowledge.
William Henry Flower the Anglican too praised evolution as a cleansing solvent, dissolving the dross which had 'encrusted' Christianity 'in the days of ignorance and superstition'.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age.
Who can tell whether the parallelogram, which in our ignorance we have defined and drawn, and the whole of whose properties we profess to know, may not be all the while panting for exterior angles, sympathetic with the interior, or sullenly repining at the fact that it cannot be inscribed in a circle?
Two Chinamen visiting Europe went to the theatre for the first time. One of them occupied himself with trying to understand the theatrical machinery, which he succeeded in doing. The other, despite his ignorance of the language, sought to unravel the meaning of the play. The former is like the astronomer, the latter the philosopher.
The greater the scientist, the more he is impressed with his ignorance of reality, and the more he realizes that his laws and labels, descriptions and definitions, are the products of his own thought. They help him to use the world for purposes of his own devising rather than understand and explain it.
To know how little one knows is to have genuine knowledge. Not to know how little one knows is to be deluded. Only those who know when they are deluded can free themselves from such delusion. The intelligent people are not deluded, because they know and accept their ignorance as ignorance, and thereby have genuine knowledge.
Ignorance itself is without a doubt a sin for those who do not wish to understand; for those who, however, cannot understand, it is the punishment of sin.
