Да нямаш книги е висша степен на умствена бедност; не достигайте дотам. - John Ruskin

Understand this clearly: you can teach a man to draw a straight line, and to carve it; and to copy and carve any number of given lines or forms, with admirable speed and perfect precision; and you find his work perfect of its kind: but if you ask him to think about any of those forms, to consider if he cannot find any better in his own head, he stops; his execution becomes hesitating; he thinks, and ten to one he thinks wrong; ten to one he makes a mistake in the first touch he gives to his work as a thinking being. But you have made a man of him for all that. He was only a machine before, an animated tool.

You should read books like you take medicine, by advice, and not by advertisement.

I believe that the root of almost every schism and heresy from which the Christian church has ever suffered, has been the effort of men to earn, rather than to receive, their salvation.
