Mirth is better than fun, and happiness is better than mirth.

Rulers and generals muster their troops. Magnates muster the sums of money which give them power. The fascist dictators muster the irrational human reactions which make it possible for them to attain and maintain their power over the masses. The scientists muster knowledge and means of research. But, thus far, no organization fighting for freedom has ever mustered the biological arsenal where the weapons are to be found for the establishment and the maintenance of human freedom. All precision of our social existence notwithstanding, there is as yet no definition of the word freedom which would be in keeping with natural science. No word is more misused and misunderstood. To define freedom is the same as to define sexual health. But nobody will openly admit this. The advocacy of personal and social freedom is connected with anxiety and guilt feelings. As if to be free were a sin or at least not quite as it should be. Sex-economy makes this guilt feeling comprehensible: freedom without sexual self-determination is in itself a contradiction. But to be sexual means — according to the prevailing human structure — to be sinful or guilty. There are very few people who experience sexual love without guilt feeling. "Free love" has acquired a degrading meaning: it lost the meaning given it by the old fighters for freedom. In films and in books, to be genital and to be criminal are presented as the same thing.

The fact that political ideologies are tangible, active realities does not prove their necessity. The bubonic plague was an extremely potent social reality. But nobody would have argued that, because it existed, it was necessary and nothing should be done about it.

The period of Catholic ascendancy was on the whole one of the most deplorable in the history of the human mind.... The spirit that shrinks from enquiry as sinful and deems a state of doubt a state of guilt, is the most enduring disease that can afflict the mind of man. Not till the education of Europe passed from the monasteries to the universities, not till Mohammedan science, and clasical free thought, and industrial independence broke the sceptre of the Church, did the intellectual revival of Europe begin.

Children are born wanting to think and discover for themselves; rote teaching systematically destroys their powers of thought; the older the students are, the less curiosity and intelligent interest you can expect.

Energy then is morally neutral, it is good or bad depending on the direction it takes. Our task is to provide legitimate outlets for it. The provision of such outlets is important in three ways - for society, for the individual and for the learning of subjects. For any society that wishes to remain civilized this is the highest priority; only by providing satisfactory activities for all citizens can delinquency, vandalism, crime and violence become exceptional rather than normal. This is a priority of which our dominant institutions seem totally unaware. For the individual, finding a satisfactory outlet for energy means a sense of fulfillment and escape from frustration. For the learning of subjects it is the driving force without which little will be learned.

To master anything from football to relativity requires effort. But it does not require unpleasant efforts, drudgery. The main task of any teacher is to make a subject interesting.

The reflection of nature in man’s thought must be understood not lifelessly but in the eternal process of movement, the arising of contradictions and their solution.

What is called happiness is an abstract idea, composed of various ideas of pleasure; for he who has but a moment of pleasure is not a happy man, in like manner that a moment of grief constitutes not a miserable one.

What has changed is that my life then was less difficult and my future seemingly less gloomy, but as far as my inner self, my way of looking at things and of thinking is concerned, that has not changed. But if there has indeed been a change, then it is that I think, believe and love more seriously now what I thought, believed and loved even then.

Ego is the biggest enemy of humans.

Harmony prevails if people of similar nature meet.

One who makes a resolution and then makes sincere efforts to realize his dreams, nothing stops him from realizing his goal.

True art is reverent imitation of God.

The secret I learned early on from my father was to run scared and never think I had it made. I never felt I was completely adequate to the job and always ran scared. The fundamental for our success was running scared.
