“The present is great with the future.”

Make me the the master of education, and I will undertake to change the world.

There is no way in which a simple substance could begin in the course of nature, since it cannot be formed by means of compounding.

In symbols one observes an advantage in discovery which is greatest when they express the exact nature of a thing briefly and, as it were, picture it; then indeed the labor of thought is wonderfully diminished.

When God works miracles, he does not do it in order to supply the wants of nature, but those of grace. Whoever thinks otherwise, must needs have a very mean notion of the wisdom and power of God.

Although the whole of this life were said to be nothing but a dream and the physical world nothing but a phantasm, I should call this dream or phantasm real enough, if, using reason well, we were never deceived by it.

Now this connection or adaption of all created things with each, and of each with all the rest, means that each simple substance has relations which express all the others, and that consequently it is a perpetual living mirror of the universe.

One cannot explain words without making incursions into the sciences themselves, as is evident from dictionaries; and, conversely, one cannot present a science without at the same time defining its terms.

God’s relation to spirits is not like that of a craftsman to his work, but also like that of a prince to his subjects.

Children are our future we must take care of them with maximum effort.

The future doesn’t frighten me, even if it threatens to be full of other difficulties.

Whatever you believe, that you will be. If you believe yourselves to be sages, sages you will be tomorrow. There is nothing to obstruct you.

It is our duty to create a social milieu in which the young and the socially weak feel that the present and future belong to them.

Children are our future we must take care of them with maximum effort.

Our words reveal our thoughts; our manners mirror our self-esteem; our actions reflect our character; our habits predict the future.

I don’t know any more about the future than you do. I hope that it will be full of work, because I have come to know by experience that work is the nearest thing to happiness that I can find. I want a busy life, a just mind and a timely death.

Life is the past, the present and the perhaps.
