It is a curious thing: man, the centre and creator of all science, is the only object which our science has not yet succeeded in including in a homogeneous representation of the universe. We know the history of his bones, but no ordered place has yet been found in nature for his reflective intelligence.

I think that man has a fundamental obligation to extract from himself and from the earth all that it can give; and this obligation is all the more imperative that we are absolutely ignorant of what limits - they may still be very distant - God has imposed on our natural understanding and power.

Progressively saved by the machine from the anxieties that bound his hands and mind to material toil, relieved of a large part of his work and compelled to an ever-increasing speed of action by the devices which his intelligence cannot help ceaselessly creating and perfecting, man is about to find himself abruptly plunged into idleness.

Religion and science are the two conjugated faces or phases of one and the same complete act of knowledge - the only one which can embrace the past and future of evolution and so contemplate, measure and fulfil them.

The Holy Ghost does not flow through methods, but through men. He does not come on machinery, but on men. He does not anoint plans, but men - men of prayer.

You don't have to go to church to be spiritual, but there are certain times in your life that you know there is a presence of something very spiritual.

Technology is nothing. What's important is that you have a faith in people, that they're basically good and smart, and if you give them tools, they'll do wonderful things with them.

Whatsoever we beg of God, let us also work for it.
