„The last thing I would say is that you can achieve a lot of things in politics and get a lot of things done; in the end, public service and the national interest is what it is all about. Nothing is really impossible if you put your mind to it. After all, as I once said, I was the future once.“

„In necessary things, unity; in doubtful things, liberty; in all things, charity (love).“

—  Aurelius Augustinus early Christian theologian and philosopher 354 - 430

The first known occurence of such an expression is as "Omnesque mutuam amplecteremur unitatem in necessariis, in non necessariis libertatem, in omnibus caritatem" in De Republica Ecclesiastica by Marco Antonio de Dominis, Pars I. London (1617), lib. 4 cap. 8 p. 676 (penultimate sentence) books.google http://books.google.de/books?id=QcVFAAAAcAAJ&pg=PA676, cf. liberlocorumcommunium http://liberlocorumcommunium.blogspot.com/2010/03/in-necessariis-unitas-in-non.html.

„In seeking there are several things involved: there is the seeker and the thing that he seeks after.“

—  Jiddu Krishnamurti Indian spiritual philosopher 1895 - 1986

Source: 1970s, p. 157
Context: In seeking there are several things involved: there is the seeker and the thing that he seeks after. When the seeker finds what he thinks is truth, is God, is enlightenment, he must be able to recognize it. He must recognize it, right? Recognition implies previous knowledge, otherwise you cannot recognize. I cannot recognize you if I had not met you yesterday. Therefore when I say this is truth, I have already known it and therefore it is not truth. So a man who is seeking truth lives a life of hypocrisy, because his truth is the projection of his memory, of his desire, of his intentions to find something other than "what is", a formula. So seeking implies duality — the one who seeks and the thing sought after — and where there is duality there is conflict. There is wastage of energy. So you can never find it, you can never invite it.
