We should not be careless toward the fulfillment of our calling.

There is no need searching for love, it cannot be found-it happens!

If you haven’t figured it out yet, an absolutely certain way to lose something as quickly as possible is to forget the privilege you have to possess it in the first place.

The only people you have to look out for in life are the people that don't care about anything or anyone. These are the people that end up teaching your children.

The rich eat life, the poor eat death; so what is the problem they ask?

It is my conviction that, with the spread of true scientific culture, whatever may be the medium, historical, philological, philosophical, or physical, through which that culture is conveyed, and with its necessary concomitant, a constant elevation of the standard of veracity, the end of the evolution of theology will be like its beginning—it will cease to have any relation to ethics. I suppose that, so long as the human mind exists, it will not escape its deep-seated instinct to personify its intellectual conceptions. The science of the present day is as full of this particular form of intellectual shadow-worship as is the nescience of ignorant ages. The difference is that the philosopher who is worthy of the name knows that his personified hypotheses, such as law, and force, and ether, and the like, are merely useful symbols, while the ignorant and the careless take them for adequate expressions of reality. So, it may be, that the majority of mankind may find the practice of morality made easier by the use of theological symbols. And unless these are converted from symbols into idols, I do not see that science has anything to say to the practice, except to give an occasional warning of its dangers. But, when such symbols are dealt with as real existences, I think the highest duty which is laid upon men of science is to show that these dogmatic idols have no greater value than the fabrications of men's hands, the stocks and the stones, which they have replaced.

Although it pains me to admit it, I am quite familiar with the holes in life. And this familiarity is due to the fact that I spend far more time in these holes than I spend on the paths that brought me to them.

Anger is useful only to a certain point. After that, it becomes rage, and rage will make you careless.

At the very point that I’ve taken something for granted, I have at that same moment taken it to its grave. And if I look around, I realize I’ve cultivated quite a cemetery.

Each day hands me a clean sheet of paper upon which to write. Therefore, I would be wise to write without ever having the need to erase.
