A well-spent day brings happy sleep.
All our knowledge has its origins in our perceptions.
Although nature commences with reason and ends in experience it is
necessary for us to do the opposite, that is to commence with experience and from
this to proceed to investigate the reason.
Anyone who conducts an argument by appealing to authority is not using
his intelligence; he is just using his memory.
Art is never finished, only abandoned.
As a well-spent day brings happy sleep, so a life well spent brings
As every divided kingdom falls, so every mind divided between many
studies confounds and saps itself.
Beyond a doubt truth bears the same relation to falsehood as light to
Blinding ignorance does mislead us. O! Wretched mortals, open your
Common Sense is that which judges the things given to it by other
Experience does not err. Only your judgments err by expecting from her
what is not in her power.
For once you have tasted flight you will walk the earth with your eyes
turned skywards, for there you have been and there you will long to return.
He who is fixed to a star does not change his mind.
He who loves practice without theory is like the sailor who boards ship
without a rudder and compass and never knows where he may cast.
He who wishes to be rich in a day will be hanged in a year.
Human subtlety will never devise an invention more beautiful, more
simple or more direct than does nature because in her inventions nothing is lacking,
and nothing is superfluous.
I have been impressed with the urgency of doing. Knowing is not enough;
we must apply. Being willing is not enough; we must do.
I have offended God and mankind because my work didn't reach the
quality it should have.
I have wasted my hours.
I love those who can smile in trouble, who can gather strength
from distress, and grow brave by reflection. 'Tis the business of little minds to
shrink, but they whose heart is firm, and whose conscience approves their conduct,
will pursue their principles unto death.
Leonardo da Vinci<
