To "learn from experience" is to make a backward and forward connection between what we do to things and what we enjoy or suffer from things in consequence.

To pull at a rope at which others happen to be pulling is not a shared or conjoint activity, unless the pulling is done with knowledge that others are pulling and for the sake of either helping or hindering what they are doing.

I believe that education is the fundamental method of social progress and reform.

That which distinguishes the Soviet system both from other national systems and from the progressive schools of other countries is the conscious control of every educational procedure by reference to a single and comprehensive social purpose.

In general it may be said that the things which we take for granted without inquiry or reflection are just the things which determine our conscious thinking and decide our conclusions. And these habitudes which lie below the level of reflection are just those which have been formed in the constant give and take of relationship with others.

We never educate directly, but indirectly by means of the environment. Whether we permit chance environments to do the work, or whether we design environments for the purpose makes a great difference.

The origin of thinking is some perplexity, confusion or doubt.
