For most of us, relationship with another is based on dependence, either economic or psychological. This dependence creates fear, breeds in us possessiveness, results in friction, suspicion, frustration.

I'm willing to make compromises based on someone I think is the one, but I think it's psychologically important to people when they're famous to be the only famous person they know.

In its famous paradox, the equation of money and excrement, psychoanalysis becomes the first science to state what common sense and the poets have long known - that the essence of money is in its absolute worthlessness.

I mean if anyone's comfortable being famous, they're a psychopath.

Religious faith depends on a host of social, psychological and emotional factors that have little or nothing to do with probabilities, evidence and logic.

In our tabulation of psychoanalytic results, we have classed those who stopped treatment together with those not improved. This appears to be reasonable; a patient who fails to finish his treatment, and is not improved, is surely a therapeutic failure.

Our failure as a society to properly acknowledge and confront the psychological, social, and political effects of white privilege has perpetuated racial inequality and race-based political resentments.

The psychology of sport is so important. When you are standing at the crease, in front of a stadium full of people, it's a pretty intense experience. So you need to have the psychological tools to control your mind and deliver your best performance.

All this talk of equality remains merely on paper. In real life, women are still bound by several psychological shackles and emotional boundaries imposed on them by their families and others. If a girl comes home late, she is asked 100 questions, whereas boys are not answerable for anything. And this prevails across segments.

The storm and stress period of women and the new social and psychological formations thereby entailed must indeed extend far into the twentieth century. This period of conflict will cease only when woman within and out of marriage shall have received legal equality with man.

Music feels so environmental to me, especially the process of working with synths or mixing. I started thinking about music as a psychological landscape as well. It's a landscape of the mind.

Psychology is much bigger than just medicine, or fixing unhealthy things. It's about education, work, marriage - it's even about sports. What I want to do is see psychologists working to help people build strengths in all these domains.

It is all nonsense, to be sure; and so much the greater nonsense inasmuch as the true interpretation of many dreams - not by any means of all dreams - moves, it may be said, in the opposite direction to the method of psycho-analysis.

I was studying psychology honours and was very happy in that zone. I had dreams of pursuing higher education. When the first film happened and another one after that, I was not sure about sticking around in this career. It was never my dream.

The truth of the matter is if we listened to our bodies and cleared our psychologies, we would inherently know what we need to do to stay healthy, and there wouldn't be a market for diet pills, extreme cleanses, or low-calorie, pre-packaged junk food.

As an industrial designer, you design the thing by yourself, and then it goes away from you, whereas fashion is in constant relation to the body and to psychology. It makes it more complicated, and it makes it more challenging.

I specialise in taking teams of designers, psychologists, usability experts, sociologists and ethnographers into the field. It's called 'corporate anthropology,' but personally I'm more comfortable with 'design research,' because I'm not an anthropologist by training.

I noticed when I was at Stanford, there was a class called the persuasive technology design class, and it was a whole lab at Stanford that teaches students how to apply persuasive psychology principles into technology to persuade people to use products in a certain way.

I'm an expert on how technology hijacks our psychological vulnerabilities. That's why I spent the last three years as a Design Ethicist at Google caring about how to design things in a way that defends a billion people's minds from getting hijacked.

Design is a way of life, a point of view. It involves the whole complex of visual communications: talent, creative ability, manual skill, and technical knowledge. Aesthetics and economics, technology and psychology are intrinsically related to the process.

It took years of psychotherapy before I even considered dating. I lost weight, replaced my glasses with contact lenses and felt a lot more confident. But I find it really hard to hold down a relationship.

It's a really deep and layered psychological situation - making music with someone - if they're trying to make something real and personal. It's almost like dating: you allow yourself to be consumed by the other - not in a bad way, but in a way that happens in nature.

Humans have continued to evolve quite a lot over the past ten thousand years, and certainly over 100 thousand. Sure, our biology affects our behavior. But it's unlikely that humans' early evolution is deeply relevant to contemporary psychological questions about dating or the willpower to complete a dissertation.

Were I to put myself on... one of those online dating things, I would not include in my profile that I'm regularly hospitalized for psychosis. But I do know that when I get really bad, there is a place for me to go where I will feel better.
