Gottfried Leibniz

To love is to be delighted by the happiness of someone, or to experience pleasure upon the happiness of another. I define this as true love.

— Gottfried Leibniz

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.

— Gottfried Leibniz

We never have a full demonstration, although there is always an underlying reason for the truth, even if it is only perfectly understood by God, who alone penetrated the infinite series in one stroke of the mind.

— Gottfried Leibniz

The love of God consists in an ardent desire to procure the general welfare, and reason teaches me that there is nothing which contributes more to the general welfare of mankind than the perfection of reason.

— Gottfried Leibniz
