"The same stimulus that animates men to action, will have a proportionate effect on juvenile minds"

This quote by Joseph Lancaster speaks to the power of inspiration and also its capability to motivate action in both grownups as well as children. He is recommending that the same stimulus, or motivating element, that urges adults to take action can also have a similar result on the minds of children. This implies that kids are equally as efficient in being motivated as well as acting as grownups, which the very same motivating aspects can be used to motivate them. Lancaster is stressing the value of giving kids with the exact same chances to be inspired as well as do something about it as adults, which the very same stimulation can be utilized to inspire both. He is recommending that children should not be ignored and that they are capable of doing something about it and also being motivated just like adults.
