For the Rays, to speak properly, have no Colour. In them there is nothing else than a certain power and disposition to stir up a sensation of this Colour or that.
Isaac Newton
Speak
One can understand nature
One can understand nature only when one has learned the language and the signs in which it speaks to us; but this language is mathematics and these signs are methematical figures.
Galileo Galilei
The difficulties in the
The difficulties in the study of the infinite arise because we attempt, with our finite minds, to discuss the infinite, assigning to it those properties which we give to the finite and limited; but this… is wrong, for we cannot speak of infinite quantities as being the one greater or less than or equal to another.
Galileo Galilei
It is very pious
It is very pious to say and prudent to affirm that the holy Bible can never speak untruth — whenever its true meaning is understood. But I believe nobody will deny that it is often very abstruse, and may say things which are quite different from wha.
Galileo Galilei
It is necessary for
It is necessary for the Bible, in order to be accommodated to the understanding of every man, to speak many things which appear to differ from the absolute truth so far as the bare meaning of the words is concerned.
Galileo Galilei
He who will please
He who will please the crowd and for the sake of the most ephemeral renown will either proclaim those things which nature does not display or even will publish genuine miracles of nature without regard to deeper causes is a spiritually corrupt person… With the best of intentions I publicly speak to the crowd (which is eager for things new) on the subject of what is to come.
Johannes Kepler
If you are silent
If you are silent, be silent out of love. If you speak, speak out of love.
Saint Augustine
