heraclitus

[rwx]

Things which are put together are both whole and not whole, brought together and taken apart, in harmony and out of harmony; one thing arises from all things, and all things arise from one thing.

(or alternatively:)

The bones connected by joints are at once a unitary whole and not a unitary whole. To be in agreement is to differ; the concordant is the discordant. From out of all the many particulars comes oneness, and out of oneness come all the many particulars.

-- Fragment 10

This world of beauty and order, the same for all, neither any God nor any man created, but it was ever and is and shall be ever-living Fire, kindled in measures and quenched in measures.

(or alternatively:)

This world-order, the same of all, no god nor man did create, but it ever was and is and will be: everliving fire, kindling in measures and being quenched in measures.

-- Fragment 30.

The way up down one and the same. ( ὁδὸς ἄνω κάτω μία καὶ ὡυτή. )

-- Fragment 60

(the alterative versions are the more technical/direct.)
