My research work was based in pictures. I needed to visualise things and projective geometry was often most useful e. g. in figuring out how a particular quantity transforms under Lorentz transf[ormation]. When I came to publish the results I suppressed the projective geometry as the results could be expressed more concisely in analytic form. (Paul Dirac)

God's Providence controls the universe. It is present everywhere. Providence is the sovereign Logos of God, imprinting form on the unformed materiality of the world, making and fashioning all things. Matter could not have acquired an articulated structure were it not for the directing power of the Logos Who is the Image, Intellect, Wisdom, and Providence of God. View quote

Unfortunately, we do not realize that when we do our work in a hurry, we become nervous. And when work is done nervously, it is not sanctified. Our goal should not be to do many things and be in constant anxiety. This is a demonic condition. What is done with calmness and prayer is blessed, and it also blesses the people who use it.

Today, universities and their researchers are ranked mainly based on the amount of funding they receive, the number of papers they publish and their intellectual caliber. ... Along with this, we should take into consideration how much we have been able to use their research to serve the lowest and most vulnerable strata of society. View quote

What they needed, in addition to many specific grievances against their particular king, was a fundamental presupposition against kings in general. What they needed was a theory of government that provided a place for rebellion, that made it respectable, and even meritorious under certain circumstances. View quote

The complete and definitive work of art is created beyond one's individuality... The universal transcends such a level. Mere spontaneity has never created a work of art which possesses a lasting cultural value. The method leading to universal form is based upon calculations of measure and number. View quote
