“Ancient science had sought knowledge of what things are, to be contemplated as an end in itself satisfying to the knower. In contrast, modern science seeks knowledge of how things work, to be used as a means for the relief and comfort of all humanity, knowers and non-knowers alike.”

Circulated on the Internet, this is an amended version of a quote from Eckhart's sermon iusti vivent in aeternum: There are simple people who imagine they are going to see God as if He were standing here and they there. This is not true. God and I are one.

Ideology and Utopia (1929)
Context: This first non-evaluative insight into history does not inevitably lead to relativism, but rather to relationism. Knowledge, as seen in the light of the total conception of ideology, is by no means an illusory experience, for ideology in its relational concept is not at all identical with illusion. Knowledge arising out of our experience in actual life situations, though not absolute, is knowledge none the less. The norms arising out of such actual life situations do not exist in a social vacuum, but are effective as real sanctions for conduct. Relationism signifies merely that all of the elements of meaning in a given situation have reference to one another and derive their significance from this reciprocal interrelationship in a given frame of thought. Such a system of meanings is possible and valid only in a given type of historical existence, to which, for a time, it furnishes appropriate expression. When the social situation changes, the system of norms to which it had previously given birth ceases to be in harmony with it. The same estrangement goes on with reference to knowledge and to the historical perspective. All knowledge is oriented toward some object and is influenced in its approach by the nature of the object with which it is pre-occupied. But the mode of approach to the object to be known is dependent upon the nature of the knower.

Context: Well, granted that it was only a dream, yet the sensation of the love of those innocent and beautiful people has remained with me for ever, and I feel as though their love is still flowing out to me from over there. I have seen them myself, have known them and been convinced; I loved them, I suffered for them afterwards. Oh, I understood at once even at the time that in many things I could not understand them at all … But I soon realised that their knowledge was gained and fostered by intuitions different from those of us on earth, and that their aspirations, too, were quite different. They desired nothing and were at peace; they did not aspire to knowledge of life as we aspire to understand it, because their lives were full. But their knowledge was higher and deeper than ours; for our science seeks to explain what life is, aspires to understand it in order to teach others how to love, while they without science knew how to live; and that I understood, but I could not understand their knowledge.
