Biologists must constantly keep in mind that what they see was not designed, but rather evolved.

Dawkins asserts that final causes and design don't really exist. Unguided evolution explains it all. Francis Crick thought the same thing but was afraid people would be misled by what they actually saw. So he issued this warning: "Biologists must constantly keep in mind that what they see was not designed, but rather evolved." What? A warning to ignore the obvious? Absolutely. Because if we don't ignore the obvious, we might be tempted to follow common sense and attribute the "appearance" of design to actual design.
Bolshevism is knocking at our gates, we can't afford to let it in...We must keep America whole and safe and unspoiled. We must keep the worker away from red literature and red ruses; we must see that his mind remains healthy.
As biologists, we contemplate with admiration and awe the wondrous array of sophisticated cell interactions and recognitions evolved in the T cell immune system, which must be a model for other similarly complex biological systems of highly differentiated organisms.
I think one of the things we must constantly keep in mind is, 'If anybody hits you on one cheek, turn the other.'
Recycling is more expensive for communities than it needs to be, partly because traditional recycling tries to force materials into more lifetimes than they are designed for - a complicated and messy conversion, and one that itself expends energy and resources. Very few objects of modern consumption were designed with recycling in mind. If the process is truly to save money and materials, products must be designed from the very beginning to be recycled or even "upcycled" - a term we use to describe the return to industrial systems of materials with improved, rather than degraded, quality.
The accomplishments in college and even in the pros are more in my mind because you constantly see Duke on TV during basketball season. You constantly see the NBA.
Evolutionary biologists often appeal to parsimony when they seek to explain why organisms "match" with respect to a given trait. For example, why do almost all the organisms that are alive today on our planet use the same genetic code? If they share a common ancestor, the code could have evolved just once and then been inherited from the most recent common ancestor that present organisms share. On the other hand, if organisms in different species share no common ancestors, the code must have evolved repeatedly.
It worries me about our unwillingness to really address reforms and modernization in Medicare. This thing was designed 37 years ago. It has not evolved to keep pace with current medical technology.
One must learn to forgive and not to hold a hostile, bitter attitude of mind, which offends those about us and prevents us from enjoying ourselves. One must recognize human shortcomings and adjust himself to them rather than to be constantly finding fault with them.
The mind is incredible. Once you've gained mastery over it, channeling its powers positively for your purposes, you can do anything. I mean anything. The secret is to make your mind work for you not against you. This means constantly being positive. Constantly setting up challenges you can meet either today, next week, or next month. "I can't..." should be permanently stricken from your vocabulary, especially the vocabulary of your thoughts. You must see yourself always growing and improving.
Proteins aren't designed, they're evolved.
One must let the play happen to one; one must let the mind loose to respond as it will, to receive impressions, to sense rather than know, to gather rather than immediately understand.
Power and those in control concede nothing ... without a demand. Hey never have and never will... Each and every one of us must keep demanding, must keep fighting, must keep thundering, must keep plowing, must keep on keeping things struggling, must speak out and speak up until justice is served because where there is no justice there is no peace.
The only way to find that territory is trying to keep your mind constantly open. That's the only way that you're ever going to see the sort of signs of where to go.
With the new technology that keeps entering the media, film composers are constantly being placed in new learning situations. Acknowledging this and realizing that one must keep up, I maintain, nonetheless, that the real creative power is in the mind and heart of the composer.
To overcome our biological limitations as individuals, we have co-evolved collective systems and capacities - cultural, social, economic, political, scientific, media, educational, public relations, etc. But the flaw in all that is that we have designed them primarily for comfort, profit, power, control, and entertainment rather than for collective intelligence, sanity, and wisdom.
