Motion and force are our primary objects of experience and consciousness; and in terms of them all other less familiar occurrences may conceivably be… - Oliver Lodge

All we know at present of locomotion is the locomotion of one piece of matter with reference to other pieces. That can be freely granted, and the whole edifice of physics is consistent with the idea that locomotion through the ether is impossible to measure. But the impossibility has never been proved, and some day an exceptional phenomenon may be found.

Death is not extinction. Neither the soul nor the body is extinguished or put out of existence. The body weighs just as much as before, the only properties it loses at the moment of death are potential properties. So also all we can assert concerning the vital principle is that it no longer animates that material organism: we cannot safely make further assertion regarding it, or maintain its activity or inactivity without further information.

The things to be investigated are either true or false. If false, pertinacious inquiry will reveal their falsity. If true, they are profoundly important. For there are no half-truths in Nature; every smallest departure has portentous consequences; our eyes must open slowly, or we should be overwhelmed.
