An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.
FRANCIS CRICKThe ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.

Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.
FRANCIS CRICK -
Again the message to experimentalists is: Be sensible but don’t be impressed too much by negative arguments. If at all possible, try it and see what turns up. Theorists almost always dislike this sort of approach.
FRANCIS CRICK -
Biologists must constantly keep in mind that what they see was not designed, but rather evolved.

It is not easy to convey, unless one has experienced it, the dramatic feeling of sudden enlightenment that floods the mind when the right idea finally clinches into place.

The balance of evidence both from the cell-free system and from the study of mutation, suggests that this does not occur at random, and that triplets coding the same amino acid may well be rather similar.

FRANCIS CRICK -
We are sometimes asked what the result would be if we put four +’s in one gene. To answer this my colleagues have recently put together not merely four but six +’s.
FRANCIS CRICK -
A busy life is a wasted life.
FRANCIS CRICK -
A theory should not attempt to explain all the facts, because some of the facts are wrong.
FRANCIS CRICK -
If the code does indeed have some logical foundation then it is legitimate to consider all the evidence, both good and bad, in any attempt to deduce it.
FRANCIS CRICK -
I also suspect that many workers in this field [molecular biology] and related fields have been strongly motivated by the desire, rarely actually expressed, to refute vitalism.
FRANCIS CRICK -
Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.
FRANCIS CRICK -
Trying to determine the structure of a protein by UV spectroscopy was like trying to determine the structure of a piano by listening to the sound it made while being dropped down a flight of stairs.
FRANCIS CRICK -
Avoid the temptation to work so hard that there is no time left for serious thinking.
