And therefore in geometry (which is the only science that it hath pleased God hitherto to bestow on mankind), men begin at settling the significations of their words; which settling of significations, they call definitions, and place them in the beginning of their reckoning.
Interpretation
This quote highlights the importance of definitions as foundational to understanding geometry and, by extension, all knowledge.
In this quote, Thomas Hobbes emphasizes that geometry, as a science, starts with the establishment of clear definitions for the terms used within it. This process of defining terms is crucial because it allows for a common understanding and a basis upon which further knowledge can be built. Hobbes suggests that this practice of defining terminology is not only applicable to geometry but is also fundamental to the pursuit of knowledge in general.
In practice
In a lecture on geometry, one could use this quote to highlight the importance of understanding foundational concepts.
Baptism is the sacrament of allegiance of them that are to be received into the Kingdom of God, that is to say, into Eternal life, that is to say, to Remission of Sin. For as Eternal life was lost by the committing, so it is recovered by the remitting of men's sins.
Force and fraud are in war the two cardinal virtues.
For it is not the shape, but their use, that makes them angels.
For to accuse requires less eloquence, such is man's nature, than to excuse; and condemnation, than absolution, more resembles justice.
Scientia potentia est, sed parva; quia scientia egregia rara est, nec proinde apparens nisi paucissimis, et in paucis rebus. Scientiae enim ea natura est, ut esse intelligi non possit, nisi ab illis qui sunt scientia praediti.
The end of knowledge is power ... the scope of all speculation is the performing of some action or thing to be done.
All political theories assume, of course, that most individuals are very ignorant. Those who plead for liberty differ from the rest in that they include among the ignorant themselves as well as the wisest. Compared with the totality of knowledge which is continually utilized in the evolution of a dynamic civilization, the difference between the knowledge that the wisest and that the most ignorant individual can deliberately employ is comparatively insignificant.
Everybody talks about the weather, but nobody does anything about it.
If you have not linked yourself to true emptiness, you will never understand the art of peace.
All things are aggregations of atoms that dance & by their movement produce sound. When the rhythm of the dance changes, the sound it produces also changes... Each atom perpetually sings its song, and the sound at every moment creates dense subtle forms.
I wrote at the start that this was a record of hate, and walking there beside Henry towards the evening glass of beer, I found the one prayer that seemed to serve the winter mood: O God, You've done enough, You've robbed me of enough, I'm too tired and old to learn to love, leave me alone forever.
They're animals, all right. But why are you so goddam sure that makes us human beings?
